In fact, they are not even inclined to perform these sacrifices. This is why, in this era, when the masses of mankind are overwhelmed by misfortune, consumed by anxiety, and disturbed by various disasters, the only recommended sacrifice is sankirtana-yajna [Any activity aimed at spreading the glories of God for the benefit of all. Its main manifestation consists of publicly chanting the holy names of the Lord, always accompanied by dancing and the distribution of consecrated food]. Indeed, the worship of Lord Krishna, the Supreme Personality of Godhead, through sankirtana-yajna is the only practice recommended for the age in which we live.
The only sacrifice we can perform today, a sacrifice that Lord Chaitanya Mahaprabhu, the Golden Avatar, recommends to us, is the chanting of the holy names of Krishna, the Supreme, Absolute, and Original Personality of Godhead.
Hare Krishna, hare Krishna, Krishna Krishna, hare hare
Hare Rama, hare Rama, Rama Rama, hare hare.
This major sacrifice, this chanting of the holy names of Krishna in Sanskrit means: O energy of the Lord, O Lord, allow me to serve you.
What are the activities that drive the soul to reincarnate?
In truth, it is activities aimed at sense gratification, whose sole purpose is to satisfy the mind and the senses, that are the cause of the spiritual being's bondage to matter and thus the imprisonment of the spiritual being in a material body. As long as the soul engages in these self-serving activities, it will continue to reincarnate from one species to another. However, let us know that the human form is rarely achieved.
The Supreme Eternal One answers: Man can enjoy the fruits of renunciation through simple self-control, detachment from worldly things, and disinterest in material pleasures. This, in fact, lies the highest perfection of renunciation.
If we want our actions to have no good and/or bad consequences, and for our karma to disappear, we must offer to God all the fruits of our actions, our existence, our life, and serve Him with love and devotion. Therein lies the perfection of existence.
Renunciation is distancing oneself from one's father, mother, brothers and sisters, wife, and children, in order to extend the love one has for them to the Supreme Lord on the one hand, and to all beings without exception on the other. It means renouncing one's social status, detaching oneself from all material possessions, and opting for total celibacy in order to love God, surrender to Him, and serve Him with love and devotion. This is perfect renunciation.
