As stated in Bhagavad-gita (3.9), yajnarthat karmano nyatra loko yam karma-bandhanah: all fruitive activities should be performed for sacrifice, which should be directed toward pleasing Krsna. As stated elsewhere in Bhagavad-gita (5.29), bhoktaram yajna-tapasam sarva-loka-mahesvaram: He is the Supreme Lord and enjoyer of everything. However, although sacrifice may be offered to please Krsna, He is more pleased when grains and ghee, instead of being offered in the fire, are prepared as prasada and distributed, first to the brahmanas and then to others. This system pleases Krsna more than anything else. Furthermore, at the present time there is very little chance to offer sacrifices by pouring oblations of food grains and ghee into the fire. Especially in India, there is practically no ghee; for everything that should be done with ghee, people use a certain type of oil preparation. Oil, however, is never recommended for offering in a sacrificial fire. In Kali-yuga, the available quantity of food grains and ghee is gradually diminishing, and people are embarrassed that they cannot produce sufficient ghee and food grains. Under the circumstances, the sastras enjoin, yajnaih sankirtana-prayair yajanti hi sumedhasah: [SB 11.5.32] in this age, those who are intellectual offer yajna, or perform sacrifices, through the sankirtana movement. Everyone should join the sankirtana movement, offering to the fire of this movement the oblations of his knowledge and riches. In our sankirtana movement, or Hare Krsna movement, we offer sumptuous prasada to the Deity and later distribute the same prasada to the brahmanas, the Vaisnavas and then to the people in general. Krsnas prasada is offered to the brahmanas and Vaisnavas, and the prasada of the brahmanas and Vaisnavas is offered to the general populace. This kind of sacrificechanting of the Hare Krsna mantra and distribution of prasadais the most perfect and bona fide way of offering sacrifice for the pleasure of Yajna, or Visnu.
