Astrology is a pseudoscience that claims to divine information about human affairs and terrestrial events by studying the movements and relative positions of celestial objects. Astrology has been dated to at least the 2nd millennium BCE, and has its roots in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Many cultures have attached importance to astronomical events, and some—such as the Hindus, Chinese, and the Maya—developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th–17th century BCE Mesopotamia, from which it spread to Ancient Greece, Rome, the Arab world and eventually Central and Western Europe. Contemporary Western astrology is often associated with systems of horoscopes that purport to explain aspects of a person's personality and predict significant events in their lives based on the positions of celestial objects; the majority of professional astrologers rely on such systems.
Jyotisha or Jyotishya is the traditional Hindu system of astrology, also known as Hindu astrology, and more recently Vedic astrology. The term Hindu astrology has been in use as the English equivalent of Jyotiṣa since the early 19th century, whereas Vedic astrology is a relatively recent term, entering common usage in the 1970s with self-help publications on Āyurveda or yoga. Vedanga Jyotishya is one of the earliest texts about astronomy within the Vedas. However, some authors have claimed that the horoscopic astrology practiced in the Indian subcontinent came from Hellenistic influences, post-dating the Vedic period. Some authors argue that in the mythologies Ramayana and Mahabharata, only electional astrology, omens, dreams and physiognomy are used but there have been several articles and blogs published which cites multiple references in those books about rashi(zodiac sign) based astrology.
In Western astrology, astrological signs are the twelve 30° sectors of the ecliptic, starting at the vernal equinox, also known as the First Point of Aries. The order of the astrological signs is Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Each sector is named for a constellation it passes through.
Astrological beliefs in correspondences between celestial observations and terrestrial events have influenced various aspects of human history, including world-views, language and many elements of social culture.
Abu Maʿshar, Latinized as Albumasar, was an early Persian Muslim astrologer, thought to be the greatest astrologer of the Abbasid court in Baghdad. While he was not a major innovator, his practical manuals for training astrologers profoundly influenced Muslim intellectual history and, through translations, that of western Europe and Byzantium.
Astrology has used the concept of classical elements from antiquity up until the present. In Western astrology and Indian astrology four elements are used: Fire, Earth, Air, and Water.
Cancer (♋️) is the fourth astrological sign in the Zodiac, originating from the constellation of Cancer. It spans from 90° to 120° celestial longitude. Under the tropical zodiac, the Sun transits this area between approximately June 21 and July 23, and under the sidereal zodiac, the Sun transits this area between approximately July 21 and August 9.
Pisces (♓️) is the twelfth astrological sign in the Zodiac. It spans 330° to 360° of celestial longitude. Under the tropical zodiac the sun transits this area between February 19 and March 20. In Sidereal astrology, the Sun currently transits the constellation of Pisces from approximately March 12 to April 18. In classical interpretations, the symbol of the fish is derived from the ichthyocentaurs, who aided Aphrodite when she was born from the sea.
Sagittarius (♐) is the ninth astrological sign, which is associated with the constellation Sagittarius and spans 240–270th degrees of the zodiac. Under the tropical zodiac, the sun transits this sign between approximately November 23 and December 21. Greek mythology associates Sagittarius with the centaur Chiron, who mentored Achilles, a Greek hero of the Trojan War, in archery.
Psychological astrology, or astropsychology, is the result of the cross-fertilisation of the fields of astrology with depth psychology, humanistic psychology and transpersonal psychology. There are several methods of analyzing the horoscope in the contemporary psychological astrology: the horoscope can be analysed through the archetypes within astrology or the analyses can be rooted in the psychological need and motivational theories. There might exist other astrological methods and approaches rooted in psychology. Astrologer and psychotherapist Glenn Perry characterises psychological astrology as "both a personality theory and a diagnostic tool".
Bangalore Venkata Raman was one of the most important astrologers in modern India and an author of numerous books and articles. He was instrumental in making Vedic or Hindu astrology known and respected throughout India and the world. With the help of his sons Niranjan Babu and Sachidananda Babu, he also started the Raman & Rajeswari Research Foundation to promote the knowledge of Astrology and Vastu Shastra.
Hellenistic astrology is a tradition of horoscopic astrology that was developed and practiced in the late Hellenistic period in and around the Mediterranean region, especially in Egypt. The texts and technical terminology of this tradition of astrology were largely written in Greek. The tradition originated sometime around the late 2nd or early 1st century BCE, and then was practiced until the 6th or 7th century CE. This type of astrology is commonly referred to as "Hellenistic astrology" because it was developed in the late Hellenistic period, although it continued to be practiced for several centuries after the end of what historians usually classify as the Hellenistic era.
The medieval Muslims took a keen interest in the study of astrology: partly because they considered the celestial bodies to be essential, partly because the dwellers of desert-regions often travelled at night, and relied upon knowledge of the constellations for guidance in their journeys. After the advent of Islam, the Muslims needed to determine the time of the prayers, the direction of the Kaaba, and the correct orientation of the mosque, all of which helped give a religious impetus to the study of astronomy and contributed towards the belief that the heavenly bodies were influential upon terrestrial affairs as well as the human condition. The science dealing with such influences was termed astrology, a discipline contained within the field of astronomy. The principles of these studies were rooted in Arabian, Persian, Babylonian, Hellenistic and Indian traditions and both were developed by the Arabs following their establishment of a magnificent observatory and library of astronomical and astrological texts at Baghdad in the 8th century.
Planets in astrology have a meaning different from the modern astronomical understanding of what a planet is. Before the age of telescopes, the night sky was thought to consist of two very similar components: fixed stars, which remained motionless in relation to each other, and "wandering stars", which moved relative to the fixed stars over the course of the year.
Mansagari is a popular classical treatise on Hindu predictive astrology. It is written in the usual poetic form in the traditional Sanskrit Sloka format; the language and the method of expression used are both simple and unambiguous, and therefore, easy to understand. Its author, Janardan Harji, about whom not much is known, was the son of Janardan, of Gurjar Mandala, who belonged to the Shandilya Gotra, who was also a learned and renowned astrologer of his time and place. This text, comprising five chapters, covers briefly the essential parts of Ganitha and Siddhanta, but deals with the Phalita portion of Hindu astrology in far greater detail. It has described numerous yogas and Raja yogas and also narrated their effects, as also the results of the planetary dashas as all major dasha systems in vogue. Along with the more renowned works of Parashara and Varahamihira, Mansagari has remained a standard reference book. The book, Three Hundred Important Combinations, was written by Bangalore Venkata Raman on the basis of Jataka Tantra, Parashara Hora Sastra and Mansagari.
Skanda Hora is the legendary first book on Hindu astrology. It is the first text and the foremost treatise of Nirayana astrology referred to as the Mahopanishad of the Atharva Veda. This text on Hindu predictive astrology written in Sanskrit Sloka-format by Skanda, also known as Subrahmanya, Kandaswamy, Kartikeyan and Murugan, is also known as Jyotishmati Upanishad
Planetary dispositors play an important role in Astrology. The dispositor is a planet in whose sign another planet is located in the natal chart and which resident planet gains strength when its dispositor is also strong.
Akhanda Samrajya yoga is a rare and highly fortunate yoga and a powerful Raja yoga that confers rulership.
Parajāta yogas are special planetary combinations or yogas that indicate birth of children who are not genetically related to their father or non-marital children or born out of illicit connections of their married mothers. Illegitimate children are stigmatized for no fault of theirs; some, like T.E.Lawrence, are made to seek redemption of their mother’s status but most accept their fate like Satyakama Jabala did. In India, illegitimate children of a Hindu father do not inherit from him on intestacy but they do inherit from their mother at par with her legitimate children.
