Bṛhaspati (Sanskrit: बृहस्पति; meaning spati of briha, the spirit of vastness of the universe written as Brihaspati) is an Indian name, and refers to different mythical figures depending on the age of the text. In ancient Hindu literature Brihaspati is a Vedic era sage who counsels the gods, while in some medieval texts the word refers to the largest planet of the solar system, Jupiter.
Bṛhaspati appears in the Rigveda (pre-1000 BCE), such as in the dedications to him in the hymn 50 of Book 4; he is described as a sage born from the first great light, the one who drove away darkness, is bright and pure, and carries a special bow whose string is Rta or "cosmic order" (basis of dharma). His knowledge and character is revered, and he is considered Guru (teacher) by all the Devas. In the Vedic literature and other ancient texts, sage Brihaspati is also called by other names such as Bramanaspati, Purohita, Angirasa (son of Angiras) and Vyasa; he is sometimes identified with god Agni (fire). His wives are Shubatreyi and Tara (or goddess who personifies the stars in the sky).
The reverence for sage Brihaspati endured through the medieval period, and one of the many Dharmasastras was named after him. While the manuscripts of Brihaspati Smriti (Bṛhaspatismṛti) have not survived into the modern era, its verses were cited in other Indian texts. Scholars have made an effort to extract these cited verses, thus creating a modern reconstruction of Bṛhaspatismriti. Jolly and Aiyangar have gathered some 2,400 verses of the lost Bṛhaspatismṛti text in this manner. Brihaspati Smriti was likely a larger and more comprehensive text than Manusmriti, and the available evidence suggests that the discussion of the judicial process and jurisprudence in Brihaspati Smriti was often cited.
Brhaspati sutras, also called the Barhaspatya sutras, is an ancient Sanskrit text named after a Vedic era sage Brhaspati, known for its theories of materialism and anti-theism. Its tenets are at the foundation of the Charvaka school of non-orthodox Hindu philosophy. The Brihaspati Sutras manuscript has been lost to history or yet to be found. However, the text is quoted in other Hindu, Buddhist and Jaina texts, and this secondary literature has been the source for reconstructing the Brhaspati sutras partially.
Some scholars suggest that Brhaspati sutras are named after Brhaspati in the Vedas, but other scholars dispute this theory because the text rejects the Vedas.
Brhaspati as a planet (Jupiter) appears in various Hindu astronomical texts in Sanskrit, such as the 5th century Aryabhatiya by Aryabhata, the 6th century Romaka by Latadeva and Panca Siddhantika by Varahamihira, the 7th century Khandakhadyaka by Brahmagupta and the 8th century Sisyadhivrddida by Lalla. These texts present Brhaspati as one of the planets and estimate the characteristics of the respective planetary motion. Other texts such as Surya Siddhanta dated to have been complete sometime between the 5th century and 10th century present their chapters on various planets with deity mythologies.
The manuscripts of these texts exist in slightly different versions, present Brhaspati's motion in the skies, but vary in their data, suggesting that the text were open and revised over their lives. The texts slightly disagree in their data, in their measurements of Brhaspati's revolutions, apogee, epicycles, nodal longitudes, orbital inclination, and other parameters. For example, both Khandakhadyaka and Surya Siddhanta of Varaha state that Brhaspati completes 364,220 revolutions every 4,320,000 earth years, an Epicycle of Apsis as 32 degrees, and had an apogee (aphelia) of 160 degrees in 499 CE; while another manuscript of Surya Siddhanta accepts the revolutions to be 364,220, but revises the apogee to 171 degrees and 16 seconds and the Epicycle slightly.
The 1st millennium CE Hindu scholars had estimated the time it took for sidereal revolutions of each planet including Brhaspati, from their astronomical studies, with slightly different results:
|Source||Estimated time per sidereal revolution|
|Surya Siddhanta||4,332 days, 7 hours, 41 minutes, 44.4 seconds|
|Siddhanta Shiromani||4,332 days, 5 hours, 45 minutes, 43.7 seconds|
|Ptolemy||4,332 days, 18 hours, 9 minutes, 10.5 seconds|
|20th century calculations||4,332 days, 14 hours, 2 minutes, 8.6 seconds|
In medieval mythologies particularly those associated with Hindu astrology, Brihaspati has a second meaning and refers to Jupiter. It became the root of the word 'Brihaspativara' or Thursday in the Hindu calendar. Brihaspati as Jupiter is part of the Navagraha in Hindu zodiac system, considered auspicious and benevolent. The word "Thursday" in the Greco-Roman and other Indo-European calendars is also dedicated to planet Jupiter (god of sky and thunder). their zodiac signs being nearly identical.
The icon of Brihaspati makes his body golden, with his legs striped blue and his head covered with a halo of moon and stars. He holds different items depending on the region. in parts of South Asia he holds a container containing soma, sometimes with a tamed tiger. Elsewhere, his icon carries a stick, a lotus and beads.[full citation needed] Brihaspati was married to Tara. In medieval mythologies, Tara was abducted by Chandra. Tara bore a son, Budha (planet Mercury).
According to some hindu mythologies once minakshi fell in love with a demon and wanted to marry him at any cost, but the demon had taken a pledge in front of Kali that he will serve the head of 11 Devine angels of heaven and after that he will be immortal and undefeatable, eventually angel minakshi was his 11th prey, unknown from his intention she left her house, her mother went to lord shanidev to save her and make her to understand, Lord shanidev tried to tell her the intention of the demon but she was determined at last shanidev went to Brahspati dev and told him to marry minakshi and he agreed, later shanidev disguised himself as a priest and brihspati dev turned into that demon and the marriage ceremony completed, after knowing this was all lie minakshi went to the demon and there she realises the truth and tries to flee from there but couldn't. Then all of the 11 angel prayed to Durga and then killed the demon.
Thursday is considered to be the dedicated day for Brihaspati. According Hindu mythology, praying to Brihaspati on Thursday provides astrological benefits.

Quote: These atheistical doctrines existed from the earliest times as their traces are visible even in the Rigveda in some hymns of which Prof Max Muller pointed out the curious traces of an incipient scepticism.
