Buddham Sharanam Gachhami!
We want Buddha to be accepted in Hinduism as Lord Vishnu's avatar.
He is called Atheist and no religion. No more insult on him can be accepted.
In the Dasavatara stotra section of his Gita Govinda, the influential Vaishnava poet Jayadeva (13th C AD) includes the Buddha amongst the ten principal avatars of Vishnu and writes a prayer regarding him as follows:
O Keshava! O Lord of the universe! O Lord Hari, who have assumed the form of Buddha! All glories to You! O Buddha of compassionate heart, you decry the slaughtering of poor animals performed according to the rules of Vedic sacrifice.
