Babasaheb Ambedkar prescribed 22 vows:
1. I shall have no faith in Brahma, Vishnu and Maheshwara nor shall I worship them.
2. I shall have no faith in Rama and Krishna who are believed to be incarnation of God nor shall I worship them.
3. I shall have no faith in Gauri, Ganapati and other gods and goddesses of Hindus nor shall I worship them.
4. I do not believe in the incarnation of God.
5. I do not and shall not believe that Lord Buddha was the incarnation of Vishnu. I believe this to be sheer madness and false propaganda.

18. I shall endeavor to follow the noble eightfold path and practice compassion and loving kindness in every day life.

20. I firmly believe the Dhamma of the Buddha is the only true religion.
21. I believe that I am having a re-birth.
22. I solemnly declare and affirm that I shall hereafter lead my life according to the principles and teachings of the Buddha and his Dhamma.
Nowadays many Ambedkarite Organisations are working for these 22 vows (i.e. 22 Pratigya). They believe that these vows only are responsible for the existence & rapid growth of present Buddhism in India. The umbrella organization known as the 22 Pledges Practice & Propagation Movement (i.e. in Hindi- 22 Pratigya Aacharan aur Prachaar Abhiyan) is fully devoted for this purpose. This totally non-political movement is the brain-child of Arvind Sontakke, and comprises around 5,000,000 volunteers (Pracharaks) including many regional and local groups throughout India.
