If one has the proper means and wealth, he should occasionally invite the devotees of Lord Caitanya who are engaged in preaching all over the world and hold a festival at home simply by distributing prasadam and talking about Krsna during the day and holding congregational chanting for at least three hours in the evening. This procedure must be adopted in all centers of the Krsna consciousness movement. Thus they will daily perform sankirtana-yajna.
