“When I say that Buddhism is a part of Hinduism, certain people criticize me. But if I were to say that Hinduism and Buddhism are totally different, it would not be in conformity with truth.”
—Dalai Lama

So who is more Buddhist than him?

The application of the Hindu Code to Sikhs, Buddhists and Jains was a historical development, and it would be too late, sociologically, to object to it. — Dr. Ambedkar

“When the Buddha differed from the Vedic Brahmins, he did so only in matters of creed, but left the Hindu legal framework intact. He did not propound a separate law for his followers. The same was the case with Mahavir and the ten Sikh Gurus.” — Dr.Ambedkar

“I will choose only the least harmful way for the country. & that is the greatest benefit I am conferring on the country by embracing Buddhism;for Buddhism is a part and parcel of Bhâratîya culture. ...++

... I have taken care that my conversion will not harm the tradition of the culture & history of this land.” — Dr.Ambedkar
