Guruगुरु

Guru is Jupiter, the fifth of the Navagraha, and is more properly Brihaspati — the preceptor (purohita) of the devas, their teacher, counsellor and priest.

His name is the word. Guru means heavy, weighty, and by extension one whose word carries weight; from this deity's role the term passed into ordinary use across Indian languages and, eventually, into English. When anyone in India speaks of their guru, they are using his name.

He is the graha of wisdom, dharma, teaching, children, prosperity and expansion, and is regarded in the astrological scheme as the most benefic of the nine — the planet whose presence improves whatever it touches. His colour is yellow, his day Thursday, and his associations run to gold, turmeric, gram and the banana tree.

His counterpart and rival is Shukra, preceptor of the asuras. The two teach opposing sides, and the tradition treats the pairing as structural rather than as a simple contest between good and evil.

Brihaspati is a genuine Vedic deity, and one of the more important ones. He appears in the Rigveda as Brahmanaspati, lord of brahman — of sacred utterance and of the power in formulated speech. Several hymns are addressed to him, and he is credited with breaking open the Vala cave to release the cows, a narrative closely parallel to Indra's slaying of Vritra.

His Vedic character is that of the divine priest: the one who knows the formulas and whose recitation makes the sacrifice effective. That is the seed of everything he later becomes — the teacher whose knowledge, rather than whose strength, is decisive.

By the epic and Puranic period he is firmly the preceptor of the devas, appearing constantly in the Mahabharata and Puranas as counsellor, and as the counterpart to Shukracharya on the asura side.

As a graha he takes his place in the Navagraha scheme in the early centuries CE, and the Brihat Parashara Hora Shastra gives him wisdom, law, teachers, children, wealth and religious observance to govern.

The Brihaspati Sutras — an ancient text associated with the materialist Charvaka school — are traditionally attributed to him, which is an odd inheritance for the priest of the gods and is generally read as a polemical attribution rather than a genuine one.

Brihaspati is shown with a golden or yellow complexion, often bearded, four-armed, and dressed in yellow.

His attributes are a teacher's rather than a warrior's: a danda (staff), a mala (rosary), a kamandalu (water pot), and a book or the gesture of instruction. Where Mangala carries a spear and Shani a bow, Brihaspati carries the implements of study and rite.

He rides an elephant — the animal of dignity, memory and deliberate movement — or a chariot drawn by eight pale horses.

As a Navagraha he faces north in the nine-planet shrine.

His gem is the yellow sapphire (pukhraj), his metal gold, his grain chana (gram), his direction northeast, and his tree the banana, which is worshipped in his name on Thursdays in much of North India.

Brihaspati — the Vedic and formal name, and the one used in ritual.

Brahmanaspati — the older Rigvedic form, lord of sacred speech.

Guru — the popular name, and the one used in astrological and devotional contexts across North India.

Devaguru — preceptor of the gods, the title distinguishing him from Shukra, the Asuraguru.

Vyazhan / Guru Bhagavan — the Tamil forms.

Jiva — a name used in astrological texts, associated with life and vitality.

He is also, in a broader sense, present in the reverence given to the human guru, and Guru Purnima honours teachers generally as much as it honours him.

Tara. His wife is taken by Chandra, the moon. Brihaspati demands her return; Chandra refuses; the gods side with Brihaspati and the asuras with Chandra, and the Tarakamaya war follows. Brahma ends it and Tara is returned, pregnant. The child, Budha, is claimed by both, and Tara names Chandra. The episode is told from Brihaspati's side as an injury, and it is one of the few narratives in which the teacher of the gods is simply a wronged husband.

Kacha and Shukra's daughter. Brihaspati sends his son Kacha to Shukra to learn the sanjivani vidya, the knowledge of reviving the dead, which the asuras possess and the gods do not. Shukra's daughter Devayani falls in love with Kacha; the asuras kill him repeatedly and Shukra revives him; finally they burn him and mix the ashes into Shukra's drink, so that reviving him would kill Shukra. Shukra teaches him the knowledge from inside his own body, Kacha emerges, revives his teacher — and then refuses to marry Devayani, who curses him. It is one of the most intricate episodes in the Mahabharata's preliminary books.

Losing his position. In one Puranic episode Brihaspati, slighted by Indra's inattention, withdraws; the gods, without a priest, are defeated, and have to install a substitute. The story functions as a statement about what the priesthood is worth.

Counselling in the epics. He appears throughout the Mahabharata as the source of political and ethical counsel, and the Brihaspati Niti material on statecraft is attributed to him.

Thursday — Guruvar or Brihaspativar — is his day, and the observances are yellow throughout: yellow cloth, turmeric, gram (chana) dal, yellow flowers, and yellow sapphire where a gem is used.

The Thursday fast is one of the more widely kept weekly observances in North India, particularly among women, and traditionally involves a single meal of yellow food and the worship of a banana tree, which is watered and marked with turmeric.

Guru Purnima, on the full moon of Ashadha, honours teachers — the human guru first, and Brihaspati and Vyasa alongside. It is observed in Hindu, Buddhist and Jain traditions, and in many schools and musical and dance lineages it is the principal annual occasion for a student to acknowledge a teacher formally.

In the Navagraha shrine he is circumambulated in the prescribed order and faces northeast.

Among those who follow Jyotisha, Jupiter's transit — the Guru Peyarchi, occurring roughly annually as he moves through a sign in about twelve months — is watched closely, and draws very large crowds to his temples in Tamil Nadu. These are beliefs held within the astrological tradition and are described here rather than endorsed.

The Brihaspati Kavacham, the Navagraha Stotra, the Guru Gita and ॐ बृं बृहस्पतये नमः are the standard recitations.

Alangudi, Tamil Nadu — his shrine among the nine Navagraha temples around Kumbakonam, and the principal Guru temple in India. The Guru Peyarchi transit draws enormous crowds here.

Guru shrines within Navagraha groups across South Indian temples.

Brihaspati temples are otherwise rare; like the lesser grahas, his worship happens chiefly within the nine-planet shrine and through the Thursday observance at home.

Banana trees in courtyards and temple precincts, worshipped on Thursdays, are in practice his most widespread site of worship in North India — an aniconic form that requires no temple at all.

Brihaspati matters most for what his name became. That the ordinary Indian word for a teacher is the name of a deity says something durable about how the culture regards teaching: not as a job but as a role with weight — guru means heavy — and one that carries obligation in both directions.

His Vedic origin is the key to his character. As Brahmanaspati he is lord of the sacred formula, the one whose correct recitation makes a rite work. Power belonging to knowledge rather than to force is his defining attribute from the Rigveda onward, and it survives intact into his astrological role as the most benefic of the grahas.

The pairing with Shukra is the most interesting structural fact about him. Gods and asuras each have a preceptor, both learned, and the asuras' teacher possesses knowledge the gods' teacher lacks — the sanjivani vidya — which is why Kacha has to be sent to steal it. The tradition declines to make the opposition a simple one between wisdom and ignorance. Both sides have a teacher; the difference is what they teach for.

And the Tara episode keeps him human. The preceptor of the gods, counsellor to Indra, source of statecraft and dharma, spends one of his best-known narratives as a man whose wife has been taken and who cannot get her back without a war. The Puranas were not in the business of protecting their teachers' dignity.
