Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Srila Sukadeva Gosvami continued: The son of Maharaja Bharata known as Sumati followed the path of Rsabhadeva, but in the Age of Kali some unscrupulous people will imagine him to be Lord Buddha himself. These people, who will actually be atheistic and of bad character, will interpret the Vedic principles in an imaginary, infamous way to
support their activities. Thus these sinful people will accept Sumati as Lord Buddhadeva and propagate the theory that everyone should follow the principles of Sumati. In this way they will be carried away by mental concoction.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Those who are Aryans strictly follow the Vedic principles, but in this Age of Kali a community has sprung up known as the Arya Samaj, who members are ignorant of the import of the Vedas in the parampara system. They decry all bona fide acaryas and pose themselves as the real followers of the Vedic principles, but in fact such non-Aryans do not follow the Vedic principles. Another group of non-Aryans are the Jains, who are referred to in the present verse. Not only do they not follow the Vedic principles, but they have no relationship with Lord Buddha, though they claim to. Imitating the behavior of Sumati, they also claim to be descendants of Rsabhadeva. Those who are Vaisnavas carefully avoid their company because they are ignorant of the path of the Vedas. In Bhagavad-gita (15.15) Krsna says, vedais ca sarvair aham eva vedyah: “The real purpose of the Vedas is to understand Me.” This is the injunction of all Vedic literatures. One who does not know the greatness of Lord Krsna cannot be accepted as an Aryan. Lord Buddha, an incarnation of Lord Krsna, adopted a particular means to propagate the philosophy of bhagavata-dharma. He preached almost exclusively among atheists. Atheists do not want any God, and Lord Buddha therefore said that there is no God, but he adopted the means to instruct his followers for their benefit. Therefore he preached in a duplicitous way, saying that there is no God. Nonetheless, he himself was an incarnation of God.
