The ultimate purpose of offering oblations in sacrifice is to please Lord Visnu. But in this Age of Kali it is very difficult to collect the different articles required for offering sacrifices. People have neither the means to collect the required paraphernalia nor the necessary knowledge or tendency to offer such sacrifices. Therefore, in this Age of Kali, when people are mostly unfortunate, full of anxieties and disturbed by various kinds of calamities, the only sacrifice recommended is the performance of sankirtana-yajna. Worshiping Lord Caitanya by the sankirtana-yajna is the only recommended process in this age.
