Ultimate reality is "the supreme, final, and fundamental power in all reality". [1] It refers to the most fundamental fact about reality, especially when it is seen as also being the most valuable fact. This may overlap with the concept of the Absolute in certain philosophies.
Anaximander (c. 610–546 BCE) believed that the ultimate substance of the universe, generally known as arche , was apeiron, an infinite and eternal substance that is the origin of all things.
Aristotle (384–322 BCE) held that the unmoved mover "must be an immortal, unchanging being, ultimately responsible for all wholeness and orderliness in the sensible world" [2] and that its existence is necessary to support everyday change.
Democritus (c. 460–370 BCE) and Epicureanism (c. 307 BCE) rejected the idea of ultimate reality, saying that only atoms and void exist, but they do have the eternal, unbounded, and self-caused nature of non-materialistic views of the concept.
In Neoplatonism (3rd century CE), the first principle of reality is "the One" which is a perfectly simple and ineffable principle which is the source of the universe, and exists without multiplicity and beyond being and non-being.
Stoic physics (c. 300 BCE–3rd century CE) called the primitive substance of the universe pneuma or God, which is everything that exists and is a creative force that develops and shapes the cosmos. [3]
In Theravada Buddhism, Nirvana is ultimate reality. [4] Nirvana is described in negative terms; it is unconstructed and unconditioned. [5]
Mahayana Buddhism has different conceptions of ultimate reality, which is framed within the context of the two truths, the relative truth of everyday things and the ultimate truth. Some traditions, specifically those who rely on the Madhyamaka philosophy, reject the notion of a truly existing or essential ultimate reality, regarding any existent as empty ( sunyata ) of inherent existence ( svabhava ). [6]
Other strands of Mahayana thought have a more positive or cataphatic view of the ultimate reality. The Yogacara school tends to follow an idealistic metaphysics. Other examples include those traditions which rely more heavily on Buddha-nature thought, such as East Asian Mahayana schools like Huayan and Tibetan traditions like shentong. [7]
In Hinduism, Brahman connotes the highest universal principle, the ultimate reality in the universe. [8] [9] [10] In major schools of Hindu philosophy, it is the material, efficient, formal and final cause of all that exists. [9] [11] [12] It is the pervasive, genderless, infinite, eternal truth and bliss which does not change, yet is the cause of all changes. [8] [10] [13] Brahman as a metaphysical concept is the single binding unity behind diversity in all that exists in the universe. [8] [14]
In Taoism, the Tao is the impersonal principle that underlies reality. It is a metaphysical principle and process that refers to how nature develops, being an enigmatic process of transformation. It is described as the source of existence, an ineffable mystery, and something that can be individually harnessed for the good. [15] It is thought of as being "the flow of the universe" and the source of its order and its qi , but it is not considered a deity to be worshipped, even if some interpretations believed it had the power to bless or illuminate.
Abrahamic conceptions of ultimate reality show diversity, in which some perspectives consider God to be a personal deity, while others have taken more abstract views. John Scotus Eriugena held that God's essence is uncaused and incomprehensible. Similarly, Maimonides believed that God is a perfect unity and is indescribable with positive attributes, and that anthropomorphic imagery in the Bible is metaphorical. [16]
Baruch Spinoza believed that God is the natural world, existing eternally and necessarily, and that everything is an effect of God's nature. He defined God as a metaphysical substance rather than a personal being, and wrote in Ethics that "blessedness" comes from the love of God, meaning knowledge of reality as it is.
Contemporary philosophy notes the possibility that reality has no fundamental explanation and should be seen as a brute fact. Adherents of the principle of sufficient reason reject this, holding that everything must have a reason.
According to Dadosky, the concept of "ultimate reality" is difficult to express in words, poetry, mythology, and art. Paradox or contradiction is often used as a medium of expression because of the "contradictory aspect of the ultimate reality". [17]
According to Mircea Eliade, ultimate reality can be mediated or revealed through symbols. [18] For Eliade the "archaic" mind is constantly aware of the presence of the Sacred, and for this mind all symbols are religious (relinking to the Origin). Through symbols human beings can get an immediate "intuition" of certain features of the inexhaustible Sacred. The mind makes use of images to grasp the ultimate reality of things because reality manifests itself in contradictory ways and therefore can't be described in concepts. It is therefore the image as such, as a whole bundle of meaning, that is "true" (faithful, trustworthy). [18] Eliade says : [19]
the sacred is equivalent to a power, and, in the last analysis, to reality. The sacred is saturated with being . Sacred power means reality and at the same time enduringness and efficacy. The polarity sacred-profane is often expressed as opposition between real and unreal or pseudoreal. [...] Thus it is easy to understand that religious man deeply desires to be, to participate in reality, to be saturated with power.
Common symbols of ultimate reality include world trees, the tree of life, microcosm, fire, children. [20]
Paul Tillich held that God is the ground of being and is something that precedes the subject and object (philosophy) dichotomy. He considered God to be what people are ultimately concerned with, existentially, and that religious symbols can be recovered as meaningful even without faith in the personal God of traditional Christianity. [21]
Buddhist philosophy is the ancient Indian philosophical system that developed within the religio-philosophical tradition of Buddhism. It comprises all the philosophical investigations and systems of rational inquiry that developed among various schools of Buddhism in ancient India following the parinirvāṇa of Gautama Buddha, as well as the further developments which followed the spread of Buddhism throughout Asia.
Idealism in philosophy, also known as philosophical idealism or metaphysical idealism, is the set of metaphysical perspectives asserting that, most fundamentally, reality is equivalent to mind, spirit, or consciousness; that reality is entirely a mental construct; or that ideas are the highest type of reality or have the greatest claim to being considered "real". Because there are different types of idealism, it is difficult to define the term uniformly.
Monism attributes oneness or singleness to a concept, such as to existence. Various kinds of monism can be distinguished:
Ātman is a Sanskrit word for the true or eternal Self or the self-existent essence or impersonal witness-consciousness within each individual. Atman is conceptually different from Jīvātman, which persists across multiple bodies and lifetimes. Some schools of Indian philosophy regard the Ātman as distinct from the material or mortal ego (Ahankara), the emotional aspect of the mind (Citta), and existence in an embodied form (Prakṛti). The term is often translated as soul, but is better translated as "Self", as it solely refers to pure consciousness or witness-consciousness, beyond identification with phenomena. In order to attain moksha (liberation), a human being must acquire self-knowledge.
Moksha, also called vimoksha, vimukti, and mukti, is a term in Hinduism, Buddhism, Jainism, and Sikhism for various forms of emancipation, liberation, nirvana, or release. In its soteriological and eschatological senses, it refers to freedom from saṃsāra, the cycle of death and rebirth. In its epistemological and psychological senses, moksha is freedom from ignorance: self-realization, self-actualization and self-knowledge.
The perennial philosophy, also referred to as perennialism and perennial wisdom, is a school of thought in philosophy and spirituality that posits that the recurrence of common themes across world religions illuminates universal truths about the nature of reality, humanity, ethics, and consciousness. Some perennialists emphasize common themes in religious experiences and mystical traditions across time and cultures; others argue that religious traditions share a single metaphysical truth or origin from which all esoteric and exoteric knowledge and doctrine have developed.
Eternity, in common parlance, is an infinite amount of time that never ends or the quality, condition or fact of being everlasting or eternal. Classical philosophy, however, defines eternity as what is timeless or exists outside time, whereas sempiternity corresponds to infinite duration.
Indian philosophy consists of philosophical traditions of the Indian subcontinent. The philosophies are often called darśana meaning, "to see" or "looking at." Ānvīkṣikī means “critical inquiry” or “investigation." Unlike darśana, ānvīkṣikī was used to refer to Indian philosophies by classical Indian philosophers, such as Chanakya in the Arthaśāstra.
Fatalism is a belief and philosophical doctrine which considers the entire universe as a deterministic system and stresses the subjugation of all events, actions, and behaviors to fate or destiny, which is commonly associated with the consequent attitude of resignation in the face of future events which are thought to be inevitable and outside of human control.
Nondualism includes a number of philosophical and spiritual traditions that emphasize the absence of fundamental duality or separation in existence. This viewpoint questions the boundaries conventionally imposed between self and other, mind and body, observer and observed, and other dichotomies that shape our perception of reality. As a field of study, nondualism delves into the concept of nonduality and the state of nondual awareness, encompassing a diverse array of interpretations, not limited to a particular cultural or religious context; instead, nondualism emerges as a central teaching across various belief systems, inviting individuals to examine reality beyond the confines of dualistic thinking.
Prakriti is "the original or natural form or condition of anything, original or primary substance". It is a key concept in Hinduism, formulated by its Sāṅkhya school, where it does not refer to matter or nature, but "includes all the cognitive, moral, psychological, emotional, sensorial and physical aspects of reality", stressing "Prakṛti's cognitive, mental, psychological and sensorial activities". Prakriti has three different innate qualities (guṇas), whose equilibrium is the basis of all observed empirical reality as the five panchamahabhootas namely Akasha, Vayu, Agni, Jala, Pruthvi. Prakriti, in this school, contrasts with Puruṣa, which is pure awareness and metaphysical consciousness. The term is also found in the texts of other Indian religions such as Jainism and Buddhism.
Ishvara is a concept in Hinduism, with a wide range of meanings that depend on the era and the school of Hinduism. In ancient texts of Hindu philosophy, depending on the context, Ishvara can mean supreme Self, ruler, lord, king, queen or husband. In medieval era Hindu texts, depending on the school of Hinduism, Ishvara means God, Supreme Being, personal God, or special Self. In Shaivism, Ishvara is an epithet of Shiva. In Vaishnavism it is synonymous with Vishnu, like in his epithet of Venkateswara. In traditional Bhakti movements, Ishvara is one or more deities of an individual's preference (Iṣṭa-devatā) from Hinduism's polytheistic canon of deities. In modern-day sectarian movements such as Arya Samaj and Brahmoism, Ishvara takes the form of a monotheistic God. In the Yoga school of Hinduism, it is any "personal deity" or "spiritual inspiration". In Advaita Vedanta, Ishvara is the manifested form of Brahman.
Generally speaking, Buddhism is a religion that does not include the belief in a monotheistic creator deity. As such, it has often been described as either (non-materialistic) atheism or as nontheism. However, other scholars have challenged these descriptions since some forms of Buddhism do posit different kinds of transcendent, unborn, and unconditioned ultimate realities.
Acosmism, held in contrast or equivalent to pantheism, denies the reality of the universe, seeing it as ultimately illusory, and only the infinite unmanifest Absolute as real. Conceptual versions of Acosmism are found in eastern and western philosophies.
The unmoved mover or prime mover is a concept advanced by Aristotle as a primary cause or "mover" of all the motion in the universe. As is implicit in the name, the unmoved mover moves other things, but is not itself moved by any prior action. In Book 12 of his Metaphysics, Aristotle describes the unmoved mover as being perfectly beautiful, indivisible, and contemplating only the perfect contemplation: self-contemplation. He also equates this concept with the active intellect. This Aristotelian concept had its roots in cosmological speculations of the earliest Greek pre-Socratic philosophers and became highly influential and widely drawn upon in medieval philosophy and theology. Thomas Aquinas, for example, elaborated on the unmoved mover in the Five Ways.
Brahmā is one of the three Gods (deva) and heavenly kings in Buddhism. He is considered one of the protectors of the teachings (dharmapala), and he is never depicted in early Buddhist texts as a creator god. In Buddhist tradition, it was the deity Brahma Sahampati who appeared before the Buddha and invited him to teach, once the Buddha attained enlightenment.
Conceptions of God in classical theist, monotheist, pantheist, and panentheist traditions – or of the supreme deity in henotheistic religions – can extend to various levels of abstraction:
In the history of religion and philosophy, deus otiosus is the belief in a creator God who has entirely withdrawn from governing the universe after creating it or is no longer involved in its daily operation. In Western philosophy the concept of deus otiosus has been associated with Deism since the 17th century, although not a core tenet as often thought.
In Hinduism, Brahman connotes the highest universal principle, the Ultimate Reality of the universe. In major schools of Hindu philosophy, it is the non-physical, efficient, formal and final cause of all that exists. It is the pervasive, infinite, eternal truth, consciousness and bliss which does not change, yet is the cause of all changes. Brahman as a metaphysical concept refers to the single binding unity behind diversity in all that exists.
