Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One should satisfy the spiritual master and assistant priests by giving them cloth, ornaments, cows and also some monetary contribution. And by distributing prasada one should satisfy everyone assembled, including even the lowest of men, the candalas [eaters of dog flesh].
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In the Vedic system, prasada is distributed, as recommended here, without discrimination as to who may take the prasada. Regardless of whether one be a brahmana, sudra, vaisya, ksatriya, or even the lowest of men, a candala, he should be welcome to accept prasada. However, when the candalas, the lower class or poorer class, are taking prasada, this does not mean that they have become Narayana or Visnu. Narayana is situated in everyone’s heart, but this does not mean Narayana is a candala or poor man. The Mayavada philosophy of accepting a poor man as Narayana is the most envious and atheistic movement in Vedic culture. This mentality should be completely given up. Everyone should be given the opportunity to take prasada, but this does not mean that everyone has the right to become Narayana.
