Maha Navami
The ninth night — the close of the nine, and the day tools, books and instruments are worshipped.
Where it is kept All India; as Ayudha Puja and Saraswati Puja in the south, Mahanavami in the east.
When it falls
Computed from the Moon's elongation from the Sun. The civil day is the one carrying the tithi running at sunrise.
Overview
The last of the nine nights. In the east it is the Navami homa and the final full worship before the immersion; in the south it is Ayudha Puja — the day the implements of a person's work are cleaned, garlanded and set aside: tools, instruments, machines, vehicles, and books.
Nothing is used on that day. The carpenter's plane, the musician's instrument, the mechanic's spanner and the student's texts are laid before the Goddess and left there until they are taken up again the next morning, on Vijayadashami.
Where it comes from
The Ayudha Puja is recorded in the Mysore Dasara and in Tamil and Telugu practice as a long-standing observance; the underlying idea — that the instrument of a livelihood is a form of the Goddess and is owed an annual honouring — appears in the Devi literature and in the royal Dasara traditions of Vijayanagara.
In the Mahabharata's Virata Parva the Pandavas retrieve their weapons from the shami tree at the end of their year of concealment, and take them up again on Vijayadashami. The Ayudha Puja and the shami worship of Dashami are connected to that episode in the tradition.
Why it matters
It is the calendar's one deliberate stoppage of work — a day on which the tools of a trade are not touched. In a working household that is the observance, more than any rite performed over them.
For students it pairs with Vidyarambham on the following day: books are put down today and a child's first letters are written tomorrow.
How to celebrate
- Clean the tools, instruments and vehicles before setting them downThe cleaning is part of the rite, not preparation for it.
- Stop using them for the dayThe abstention is the observance.
- Place the books before the GoddessSaraswati Puja in the southern reckoning falls here.
- Perform the Navami homa if your tradition keeps itThe concluding fire offering of the nine nights.
What to avoid
These are not all the same kind of thing. Some are prohibitions from a named text, some are Indian law, some are practical, and some are a confusion worth not repeating. Each item says which it is.
- Do not use the implements you have offered until the next morningTaking them up again is Vijayadashami's act, not today's.
- Do not read the books you have placed for the pujaThe same rule; they are taken up at Vidyarambham.
- Do not break the Navratri fast before the Navami rites are completeParana follows the concluding worship.
