In other words, sacrifice is acting for the satisfaction of the Supreme Lord, Krishna.

Let us understand that all our thoughts, words, and actions generate positive or negative effects, which will inevitably lead to beneficial consequences for the positive effects and painful ones for the negative effects. As soon as we act for our own pleasure, in a selfish and personal manner, we must also accept the consequences that follow. We ourselves are the cause of our own suffering.

Let us carefully understand that any act performed other than sacrifice binds its doer to matter and keeps him imprisoned in this material world. If we do not act for the satisfaction of the Supreme Lord, Krishna, then we will be chained to the consequences of our actions. We must not act for our own pleasure, but for God's.

This is what is meant by true sacrifice.

Truly, all divine beings, all celestial beings, are satisfied when a sacrifice is performed. Indeed, celestial beings rely on the sacred meal offered to God during these sacrifices, hence their necessity.

Materialists who engage in acts aimed at gratifying the senses must perform sacrifices, otherwise they will chain themselves to the consequences of their actions.

Performing a sacrifice is a truly arduous task, for one must invite all divine beings. In this present age, one of discord, quarrels, hypocrisy, indifference, and sin, it is not possible to perform such costly sacrifices, nor to invite celestial beings to participate in them. Therefore, the original holy scriptures indicate that in the present age, intelligent people must understand that it is impossible to perform Vedic sacrifices. Yet, unless one pleases the divine beings, there can be no regularity in the course of the seasons or in the rains, for they are the ones who direct all natural phenomena. In this age, therefore, in order to maintain peace and prosperity in society, all intelligent people should perform the only appropriate sacrifice by chanting the holy names of the Lord's hymn:

hare Krishna, hare Krishna, Krishna Krishna, hare hare

hare Rama, hare Rama, Rama Rama, hare hare

The names of God that compose the chant “Hare Krishna” are specifically intended to counteract the terrible consequences of the present age, the age of discord, hypocrisy, quarrels, indifference, decadence, and sin. No method of spiritual realization can be found for the present age as sublime as this chant, this major sacrifice, this chanting of the Holy Names of Krishna in Sanskrit, which means:

O Lord, O energy of the Lord, O Source of all happiness, please make me your beloved servant, allow me to serve you.

Krishna and Rama are the Holy Names of God, and Hare is none other than his internal energy, his energy of bliss.
