Vow to take only prasada

The difference of cooking here in this temple and in an ordinary
house is that in an ordinary house they’re cooking sins. The cooking appears
the same, but here there is no sin, because it is being cooked for Krsna.
Beyond this field of activities, Krsna consciousness, everything is within
the laws of nature, generally, you are being implicated in sinful
activities. And those who are little more cautious, they avoid sinful
activities, they do pious activities. But even in pious activities, one is
implicated.

So we should be careful not to eat anything which is not offered to
Krsna. That should be our determination. We cannot purchase things from the
market and eat. No. That is not possible. We cannot eat. We can simply eat
such things which are offered to the Deity, Krsna. Even if we have committed
some sin, by eating this prasadam we counteract it. How is this? That is
also stated in the Bhagavad-gita. [Bg. 18.66] “If you surrender unto Me,
then I’ll give you protection from all sinful reactions.”

So if you make it a vow that “I shall not eat anything which is not
offered to Krsna,” that means surrender. You surrender to Krsna, that “My
dear Lord, I shall not eat anything which is not offered to You.” That vow
is surrender. And because there is surrender, you are protected from sinful
reaction.
