Amavasya means day of darkness where the role of evil spirit covered the earth surface. Kaushiki Amavasya is the day when tantriks celebrate it across the West Bengal. It is mainly popular in Tarapith where sadhus and tantriks worshipped for the spirit.
The annual festival of Tarapith is KaushikiMela which is also the annual event of Maa Tara, held on the Amayasya night. Every August it celebrated at Tarapith near Rampurhat (Bhirbum District) in West Bengal.
This tithi contains some important meaning and values. And peoples who believe in MATRI SHAKTI they usually pay for the worship of Kalimata specially MAA TARA. In this day, tantriks believed that the gateway of heaven and hell is open for some time. Many saints and tantriks descend upon Tarapith every year and lakhs of devotees throng the area.
It is believed that a fast on this particular Amavasya would ward off widow-hood in women and to ensure Progeny. It is also believed that all desires could be fulfilled if one fasts on such an Amavasya.
Every month, the new-moon day is considered auspicious for the worship of forefathers and poojas are made. However, no travel ought to be scheduled the first day of the new moon. Religious people are believed to not work and concentrate on the rites function on Amavasya. Even today traditional workers like masons do not work on Amavasyas in India. However they will work on Saturdays and Sundays. Amavasya was traditionally monthly off day.
The Amavasya function is usually done in the afternoon at home (hence travel and daily work are postponed). Even High Court judges of 18th century in India used to observe Amavasya as off day. It was the British Rule that brought Sunday off principle to Indian industry.
On Amavasya ‘Torpon’ is done for forefathers by Brahmins whose father has died earlier. Nowadays a short 20-minute version of the ceremony is done—offering black sesame and water as oblation to departed souls.
This oblation is offered to father, grandfather and great grandfather at 3 levels. Then oblation is offered to mother, grandmother and great grandmother at next 3 levels. Similarly this is done to mother’s side of the family also. If one of these persons is still alive, their name is skipped and the corresponding earlier generation person is offered oblation. Then a final oblation is offered to those anonymous souls which died and have nobody in their lineage offering oblation. These oblations are believed to give birth to good children without mental or physical challenges (so say the prayers in this function).
Kaushiki is a Hindu Goddess. She is an affiliation of Shakti and a form of Parvati Devi. Her beauty had attracted many asuras who met her as messengers in her glittering beautiful palace. She was a great woman warrior, raised on her fierce lion or tiger. As in the MatsyaPurana, Goddess Parvati once performed austerities and meditation to become fair (Gouri).
It is said that from the skin she sloughed off from her body emerged the beautiful and dark-complexioned goddess Kaushiki. After that, Kaushiki went to Vindhyas and slayed Shumbha and Nishumbha, two demons who had gained the boon of immortality from Brahma.
