Sacrifice means to please the Supreme Lord. krishna

vasudeve bhagavati
bhakti-yogah prayojitah
janayaty asu vairagyam
jnanam ca yad ahaitukam
[SB 1.2.7]

Just, for example, that we are eating. Eating is necessary. So long my body is there, eating is necessary. So in the Bhagavad-gita it says,

yajnarthat karmano 'nyatra
loko 'yam karma-bandhanah
yajna-sistasinah santo
mucyante sarva-kilbisaih
[Bg. 3.9]

that one who performs sacrifice... Sacrifice means to please the Supreme Lord. That is the sacrifice, meaning of sacrifice. Otherwise sacrifice has no meaning. Sacrifice means... Suppose you have got one thousand dollars in your pocket. Now you sacrifice it. You spend it for some good cause. "Oh, this man has sacrificed one hundred dollars." But that sort of sacrifice is also cause of your bondage. Now, suppose you have given to a poor man one hundred dollars to help. Now, the, according to law of karma, you have given one hundred dollars to a poor man to help him. This means that the poor man has to pay you four hundred dollars in your next life, with interest and compound interest. And you will have to take that four hundred dollars. And suppose you are preparing yourself to conquer over the next life, but by contributing this one hundred dollars you are now bound up to take payment of four hundred dollars; therefore you have to take your birth. These are subtle laws. If we are to believe the Vedic literature, the law of karma, these are stated there. We may take it or not take it. That is a different thing. Just like if you deposit in the bank one hundred dollars. So if you forget, twenty years after you will have to take two hundred dollars. The bank will pay you, either you like to take it or not take it. Just like we have this law in this ordinary life, similarly, anything, good action or bad action, we have to suffer or enjoy the result. That is called reaction. But sacrifice for the cause of the Supreme Lord, that has no reaction. This is also bright side. There are so many wrong side also.

So Bhagavad-gita says that yajna-sistasinah santo mucyante sarva-kilbisaih. Sarva-kilbisaih. Sarva-kilbisaih. Kilbisa means sinful reaction, sinful reaction, "Tit for tat," good reaction or bad reaction. But one who eats after offering to the Supreme Lord, he is not under the regulation of reaction. Whatever we eat... Even we eat, that, we have got to repay for that. Now, the Sanskrit word, the flesh... Flesh, Sanskrit word, is called mamsa. Mamsa. The mamsa means..., mam means "me," and sa means "he." "So I am eating some animal; so in my next life that animal will eat me." That is called mamsa. So now, apart from animal... Don't think that those who are vegetarian, they are free from all these reaction. No. They are also. They are also. The law is that one has to repay which he is taking the help from other living entities. That is the law of karma. So either you eat vegetables or either you eat flesh, you have to repay that. But yajna-sistasinah santo mucyante sarva-kilbisaih. The Bhagavad-gita says that if you eat the remnants after offering sacrifice to the Lord, then you, not only you are free from all reaction, but you do not eat anything sinful. That is the direction of Bhagavad-gita.

So in every aspect of our life... This is also one of the insignificant example of our activities of our life. If we act, dovetailing our actions with the Supreme Lord, then we are free from reaction. Otherwise we are bound up by the reaction. That is the law. So in order to get myself free from all reaction of my activities.. . Because so long I am... Because I am living entity, I have to act. Either I act spiritually, either act materially, I have to act. My activities will not stop. It is foolishness to say that "I will stop my activities." No. That cannot be. Your activities will go on. If you don't act spiritually, then you have to act materially. And if you are fully engaged in spiritual activity, then there is no chance of material activity. Because after all, you are actor, one, if you are engaged in something. Just like in our ordinary life, if we do something at a particular moment, we cannot do other things; similarly, we have to engage ourselves fully in the spiritual life. Then our material activities will be stopped altogether, and then there will be no reaction. In spite of our acting... Just like the soldier. In spite of his killing hundreds and thousands of people, he is not to be hanged; he is to be rewarded. This is the technique.

Hare means the energy of the Lord, and Krishna means the Supreme Personality of Godhead

Excerpt from lecture, Montreal, June 15, 1968

So what is this Hare Krishna? Hare means the energy of the Lord, and Krishna means the Supreme Personality of Godhead. So it is a prayer. There are three words only: Hare, Krishna and Rama, three words. That has been arranged in sixteen words: Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. So our movement is that we request you to take up these sixteen words—not sixteen words, three words, Hare, Krishna, Rama. But is is arranged in such a way that there are sixteen words. So anyone can take it by heart, these three words, and chant it. It is universal. And if you think that "Oh, Krishna is the name of Hindu god," if you have got any objection, then you may not chant Krishna, but you must have a name for God. Just like somebody, the Muhammadans, call Allah, the Jews call Jehovah, or somebody calls something. That doesn't matter. If you think that "Why shall I chant the Indian name Krishna, Sanskrit name Krishna?" so Lord Chaitanya says that there are millions and billions of names of God. If you think that this Krishna name is not very suitable, you can accept any name. That doesn't matter. Our proposition is you chant God's name. That is our proposal. Therefore it is universal. If you like, you can chant Jehovah or you can chant Allah, but we request you that you chant God's name. Is it very difficult? It is not at all difficult. Lord Chaitanya said that there are innumerable names of God according to different languages, different countries, different societies. And each and every one of them has the potency of God Himself. If there is any God, so God is Absolute; therefore there is no difference between His name and He Himself. Just like in the material world, in the world of duality there is difference between the name "water" and the substance water. The name water is different from the substance water. If you are thirsty, if you simply chant, "Water, water, water, water," your thirstiness will not be quenched. You require the substance water. That is material, but spiritually, the name Krishna or the name Allah or the name Jehovah is as good as the Supreme Personality of Godhead.

Therefore if you chant Hare Krishna... You may inquire why we are chanting Hare Krishna. Hare Krishna, this name, was chanted by Lord Chaitanya, who introduced this movement five hundred years ago in India. We are following the footprints of Lord Chaitanya. Because He chanted Hare Krishna, therefore we are chanting Hare Krishna. But Lord Chaitanya has recommended that God has innumerable names, and any one of them can be chanted, and there is no hard and fast rules and regulations for chanting. It is not that you have to prepare yourself or you have to educate yourself or you have to adjust yourself for chanting. No. Everyone. Just like immediately we began to chant. You were not prepared, but you joined with us, you clapped with us, you danced with us. So similarly, there is no preoccupation or any rules and regulation. You simply chant. And this is very easy. While walking, you can chant whatever name you like. We like Krishna. We chant always: Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. While walking the streets, while you are going in the bus, and whatever, even while working with your hands, you can chant. There is no loss on your part. There is no expenditure on your part, but the gain is very great. Why don't you try it? Try it. That is our request.
