The influence and prestige of Buddhism in Bengal increased from the 8th to the 9th century AD and was finally established during the reign of the Pala kings. Religion Buddhism The Pala kings were able to eradicate Hinduism from all over eastern India. Although there is no mention of idolatry in the early stages of Buddhism, idols of many gods and goddesses later entered the religion. In Bengal, in the Buddhist era, the religion of the common people was changed, but the reform folklore remained. In many cases, various ancient folk deities began to be worshiped here according to the Buddhist Tantra mantra. Mahamaya, Kalitara, Bhadrakali, Rakshakali, Shmashan Kali, Ratanti Kali etc. were worshiped in different parts of India especially in Bengal. In this way Kali Puja has been performed in a very ritualistic manner for ages.
