Thursday — *Guruvar* or *Brihaspativar* — is named for Brihaspati (Jupiter), the *guru* of the *devas* and the planet of wisdom, faith, ethics, dharma, teachers, and higher learning. The Thursday vrat is widely kept by students, those preparing for examinations, those seeking children, and those who feel a need for clearer ethical direction in life.
✦ Why Brihaspati on Thursday?
In classical Vedic astrology Jupiter is the *naisargika karaka* (natural significator) of *jnana* (knowledge), *putra* (children), *dharma* (right conduct), and *guru* (teacher). His weekly day is given over to remembering and cultivating these themes.
✦ A Day's Routine
- 1**Morning bath**, **yellow clothes** — yellow is Jupiter's colour and is worn by both worshippers and offered to the deity.
- 2**Puja** — at the home shrine or a Vishnu / Brihaspati temple. The traditional offerings are: yellow flowers, *chana dal* (yellow split gram) and *gud*, a *peepal* leaf, turmeric (*haldi*) — applied as a tilak to a banana plant if one is available, since the banana is sacred to Brihaspati.
- 3**Mantra** — the Brihaspati beej mantra *Om Brim Brihaspataye Namah* (108 repetitions) or the longer Brihaspati gayatri.
- 4**Light fast** — many take a single meal in the evening, vegetarian, with chana dal and yellow rice. Salt is sometimes avoided in stricter observance.
- 5**Reading** — the *Vrihaspati Vrat Katha* (a short Hindi-language story narrating the vrat's traditional fruits) is read or listened to.
- 6**Charity** — yellow items, books to a student, a donation toward education, a donation to a teacher in difficult circumstances. Educational charity on Thursday is traditionally the most appropriate.
✦ What is Avoided
Banana, the fruit specifically associated with Brihaspati, is not consumed on a Thursday by those keeping the vrat — it is offered, not eaten. Hair-cutting and nail-cutting are also traditionally avoided on Thursday (this is a wider rule, not specific to vrat-keepers, with origins in older texts on personal grooming days).
✦ What the Vrat Cultivates
Beyond the prayer for a specific outcome, the vrat is — at its heart — a weekly turn toward *dharma*. A few hours given over to reading something serious, to honouring one's teachers, to helping a student, to deepening one's commitment to one's own ethical line. Brihaspati's grace, in classical understanding, flows toward those who already lean in this direction.
