Nirguna Brahman and Saguna Brahman are two complementary concepts in Hindu philosophy, particularly within the Vedanta tradition, used to describe the nature of the ultimate reality, Brahman.
Nirguna Brahman refers to Brahman without attributes, qualities, or form. It is the unmanifest, infinite, and formless reality beyond empirical perception. The Bṛhadāraṇyaka Upaniṣad uses the method of neti neti ("not this, not that") to express the ineffability of Nirguna Brahman. [1]
The Māṇḍūkya Upaniṣad identifies Nirguna Brahman with Turiya, the fourth state of consciousness beyond waking, dreaming, and deep sleep. [2]
In Advaita Vedanta, articulated by Adi Shankaracharya, Nirguna Brahman is the sole absolute reality (paramārthika satya). Liberation (moksha) is attained through the realization that the individual self (Ātman) is identical with Nirguna Brahman. [3]
Saguna Brahman refers to Brahman with form and attributes, expressed through deities such as Vishnu, Shiva, or Devi. This concept supports devotional worship (bhakti), making the divine accessible to human understanding. The Bhagavad Gītā acknowledges both forms of Brahman, stating that devotion to the manifest is easier for most aspirants, though the unmanifest is also valid. [4] [5]
In the Bhagavad Gītā (10.8; 18.61), Krishna identifies himself as the origin of all beings and as residing in the hearts of all. [6]
According to Advaita Vedanta, Saguna Brahman is a lower, provisional reality—an appearance of Nirguna Brahman through Māyā. It functions as an aid to meditation and devotion, but is ultimately transcended when the aspirant realizes the non-dual truth. [7]
Vishishtadvaita Vedanta, as taught by Ramanuja, asserts that Brahman is inherently Saguna, possessing infinite auspicious qualities. In this school, the term "Nirguna" refers only to the absence of negative qualities, not the absence of all qualities. [8]
