In this age if you perform this congregational chanting, there is no expenditure. It is not the question of that you have to go somewhere out of your house — even in your house. You just keep one picture of Caitanya Mahaprabhu, Nityananda, and the family members sit down, around. Just like we are sitting now and chanting: Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare. This kind of performing yajna, is there any expenditure? Or is there any loss? But you can perform yajna daily, twice, thrice. This is our preaching. Krsna consciousness movement means that every householder, every man — not only householder; factory holder, every holder — they can perform this sankirtana-yajna anywhere. If you can distribute some prasadam side by side, it is very good. Even if you do not distribute prasadam, simply chant this Hare Krsna mantra, then your life is successful.
