Guru Purnima (Vyas Puja)

Guru Purnima is the full moon (Purnima) of the Shukla paksha in the Ashadh month — a day to express respect and gratitude toward one's guru (teacher or guide). It is also called Vyas Purnima, since it's regarded as the birth anniversary of Maharshi Vyasa — who divided the Vedas into four parts and composed the Mahabharata, earning him the title of Adi-Guru (the first guru). This year (2026): Wednesday, 29 July.

This year's dates (2026)

This is a day honouring the guru-shishya tradition, and beyond Hindu tradition, this Purnima also holds significance in Buddhist and Jain traditions. In Maharashtra, it carries special weight within the Datta sampradaya.

Significance

In Indian tradition, the guru is regarded as a guide toward knowledge, sadhana, and spiritual growth — "one who dispels the darkness of ignorance." Guru Purnima is the principal day for expressing gratitude toward that guru-tattva (the guru principle).

Vyasa compiled the scattered Vedic knowledge and divided it into the four Vedas (Rig, Yajur, Sama, Atharva), teaching each to one of his four disciples (Paila, Vaishampayana, Jaimini, Sumantu), and composed the Mahabharata and the eighteen Puranas — which is why he's regarded as the primary organizer of humanity's knowledge tradition.

This Purnima falls close to the start of Chaturmas (the roughly four-month monsoon period) — in ancient times, disciples would live near their guru's ashram during this period for intensive study; in the sannyasi tradition too, this marks the start of a period of monsoon residence and study. Ashadhi Ekadashi (the start of Chaturmas) falls in this same Ashadh month. As a guru-parva in the Datta tradition, it also shares a conceptual link with Datta Jayanti (in Margashirsh).

Vyasa's life story

This is not a vrat-katha — it presents Vyasa's life story and his significance as the Adi-Guru.

Vyasa was the son of sage Parashar and Satyavati (a fisherwoman's daughter). Because he was born on an island (dwipa) and was dark-complexioned, he is called "Krishna Dwaipayana." He compiled the scattered Vedic verses and divided the single, eternal Veda into four parts, teaching one each to his four principal disciples (Paila, Vaishampayana, Jaimini, Sumantu). Tradition credits Vyasa with composing the Mahabharata (including the Bhagavad Gita within it), the eighteen major Puranas, and the Brahma Sutras. Vyasa is regarded as a partial avatar of Vishnu, and one of the seven Chiranjivis (immortals who are held to still be alive in the Kali Yuga).

Worshipping Vyasa as the Adi-Guru — along with one's own guru lineage — on Guru Purnima is called "Vyas Puja"; many ashrams and mathas hold a veneration of Vyasa, discourses, and remembrance of the guru tradition on this day.

Who observes it, and how

Disciples and devotees seek darshan of their living guru and receive blessings through worship and veneration; in the guru's absence, Vyasa or one's chosen deity is worshipped instead. Temples, ashrams, and mathas hold Vyas Puja, discourses, and bhajan-kirtan. It is also viewed, in a broader sense, as a day to express gratitude toward teachers, mentors, and gurus of music or dance.

Puja vidhi (guru worship)

The order varies by tradition and sampradaya; what follows is a researched general order, not a fixed universal one.

  1. An early morning bath (traditionally at Brahma-muhurta) and clean clothes; clean the puja space and spread a yellow or white cloth, on which an image of the guru, Vyasa, or one's chosen deity is placed.
  2. Offer a lamp and incense, sandalwood paste-akshata-flowers, and fruit or naivedya; recite a guru stotra or guru-vandana in remembrance of one's sadhana.
  3. If a living guru is present, perform pada-puja (worship of the guru's feet) and receive blessings; otherwise, offer prayers to an image or to Vyasa.
  4. Guru dakshina — traditionally offered to the guru (money, but more importantly, service, respect, and living out the teaching).

Since this is an annual day of gratitude, it doesn't carry a single concluding rite the way a vrat does. In the Datta tradition, it's customary to recite the Gurucharitra for the preceding seven days (Gurucharitra saptah).

Fasting & food

A strict fast isn't required on Guru Purnima; it is mainly a day of guru-reverence and worship. Some devotees observe a Purnima fast or sattvic food out of personal faith, but this is individual and tradition-dependent — it can vary by household and local custom.

Mantra & shloka

Guru Purnima's best-known shloka — recognizable by its opening line, "Gururbrahma Gururvishnu…" — carries the sense that the guru is like Brahma, Vishnu, and Maheshwar; the guru is the very embodiment of the supreme reality, and salutations are offered to that guru. This shloka is regarded as belonging to the Guru Gita (within the Skanda Purana tradition, a dialogue between Shiva and Parvati). While the Guru Gita and this shloka are popularly said to have been composed by Vyasa, its exact place within surviving Skanda Purana manuscripts is uncertain, so it is presented here neutrally as "a well-known shloka from the Guru Gita (in the Skanda Purana tradition)." In the Datta tradition, "Om Namostute Vyasa…" is also recited as a salutation to Vyasa.
