The formula is that we have to become detached from the result of the work and must be situated in full knowledge. In full knowledge. Unless we are situated in full knowledge, it is not possible to be detached from the work which you are doing. And that detachment and that knowledge, to be situated in full knowledge, is possible when we perform yajña, or sacrifice.
Now, today's subject matter is varieties of sacrifices, how we can perform different kinds of sacrifices. And what is the sacrifice? Sacrifice means yajñārthe karma. Just at the present moment our conception is that I am the proprietor of everything. Actually, I am not the proprietor. The Īśopaniṣad says that īśāvāsyam idaṁ sarvam (Īśo mantra 1). "The Supreme Lord, Personality of Godhead, or Kṛṣṇa, He is the proprietor." But by deluded by the illusory energy of the material existence, we are thinking that "I am the proprietor." Therefore in the scriptures, in Vedic scriptures, sacrifice is recommended.
Sacrifice means you give voluntarily. You give voluntarily. Because we have been so much attached to this material proprietorship, that . . . and without that attachment, there is no possibility of our becoming free from this material entanglement. But that attachment is very difficult to give up. Therefore sacrifice has been recommended, that "You sacrifice." You . . . it is . . . supposing that it is your proprietorship, you are the proprietor of everything, but you sacrifice, yajñārthe. Yajñārthe means "for the Supreme Lord."
So, so many sacrifices are recommended in various scriptures. So we shall try to discuss some of the sacrifices. Yajñāyācarataḥ karma samagraṁ pravilīyate (BG 4.23) . If we perform our duties, yajña, for the matter of satisfaction of Viṣṇu, the Supreme Lord, then we shall not be bound up by the reaction of any work.
Now, that first thing is in the sacrifice according to the Vedic rites, there are five principal factors. What are those? There is sacrificial fire, altar, and the person who is offering the . . . generally, in the sacrifice grains and butter, clarified butter, is offered. So the sacrificial altar, fire, and the offering ingredients, grains and clarified butter, and the person who is offering sacrifice, three, and the result and the performance. These five things are there in the matter of sacrifice.
Now, Kṛṣṇa says that if these five things are transformed into Kṛṣṇa consciousness or Brahman realization, then the result will be that the man who is performing that sacrifice is sure to attain his spiritual salvation and go back to Godhead.
