People are mad, and they are doing anything mischievous, sinful. And what is the purpose? Now, just to satisfy the senses. You see? There are so many nice foodstuff—Kṛṣṇa has given—fruits, flowers, grains, milk, butter, sugar. And you can prepare hundreds and thousands of preparation out of it and offer to Kṛṣṇa and eat it very nicely. "No. We must have meat." This is vikarma. Vikarma means sinful activities. Karma, vikarma, and... Tena tyaktena bhuñjīthā (ISO 1). God has given you so many nice foodstuff. Why should you kill an animal? Therefore Jesus Christ says, "Thou shall not kill." "Then shall I die?" No. There are so many things. You eat. Tena tyaktena, whatever is ordained by you, by God, Kṛṣṇa... The same thing is said. Kṛṣṇa should have said, "Give me..." Mamsam din mam.(?) No. He says, patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati (BG 9.26).
So this is yajña, to satisfy Kṛṣṇa. So if you offer Kṛṣṇa these things, what He wants, you will satisfy. Yo me bhaktyā prayacchati. Bhaktyā, with bhakti, Kṛṣṇa said. So why don't you do this? That is yajña. Everyone can perform yajña at home. Because they are eating. Who is there who is not eating? Everyone is eating. But if you prepare, within these items, patraṁ puṣpaṁ phalaṁ toyam, and prepare nice varieties of foodstuff and offer to Kṛṣṇa, that is yajña. That is yajña. And yajña-śiṣṭāśinaḥ santo mucyante sarva-kilbiṣaiḥ. If you take prasādam, Kṛṣṇa will not eat everything. He will eat, and He will leave for you also. So don't be afraid that "If I offer Kṛṣṇa, He will take away." (laughter) Kṛṣṇa is not so hungry. Even if He is hungry, He can eat the whole universe. So just satisfy Kṛṣṇa. "Sir, it is all given by You, the food grains, these fruits, flowers. It is Your gift. So You first of all taste or eat. Then I shall eat." Kṛṣṇa is very satisfied. So we want Kṛṣṇa's satisfaction. Svanuṣṭhitasya dharmasya saṁsiddhir hari-toṣaṇam (SB 1.2.13). You have cooked very nicely, and if Kṛṣṇa says, "Yes, it is very nice," then your cooking is perfection. Saṁsiddhir hari-toṣaṇam (SB 1.2.13).
So do anything. If Kṛṣṇa is satisfied, that is yajña. That is yajña. And one should live for that purpose. Yajñārthe karmaṇo 'nyatra loko 'yam. Work very hard, but yajñārthe. And if you work so hard like ass and cats and dog simply for satisfying your tongue or belly or the genital, a straight line, then you are going to hell. Yajñārthe karmaṇaḥ anyatra karma-bandhanaḥ. Then you are becoming bound up by the laws of nature. If you eat and sleep and act like dog, then become dog next life. And if you act like god, then you'll get god, very easy thing. So whatever you like, you can do. But the śāstra gives you direction, yajñārthe. "Act, work, work hard for pleasing the Supreme Lord." Yajñārthe. Otherwise you will be bound up in the cycle of birth and death. Don't do it.
So this Kṛṣṇa consciousness movement is teaching this education, that perform... You cannot escape it. You cannot say that "You are interested. You can do. We are not interested." If you are not interested, then you are living a very risky life because you have to change your body. Dehāntaram. You can see. There are examples of so many types of body. Now, suppose if you live at the risk of your life and next life you become a tree, stand up for five thousand years in the snow, scorching heat, scorching, blasting and so many disturbances, and you cannot move an inch, and people may cut down you, your leaves, your trunk, or you, they are cutting so many... What is that life? And if you think, "No, I am living for five thousand years," what is the use of living such five thousand years? No. Don't risk life. Karma-bandhanaḥ. If you don't perform yajña, if you don't try to satisfy the Supreme Lord... Just like if you don't try to satisfy the government, then it is your risky life. You cannot say that "I am living very happily." Because you are cheating government or do not following the laws of the government, that is very risky life. Similarly, if you do not perform yajña, you cannot avoid it. Saha-yajñāḥ prajāḥ sṛṣṭvā. You are, you have got this human form of life for performing yajña.
So in this age, in Kali-yuga, it is very difficult to perform other yajña. Therefore Caitanya Mahāprabhu, Kṛṣṇa, has appeared to accept your yajña, to deliver you, and the yajña process is very easy: yajñaiḥ saṅkīrtanaiḥ. That's all. Simply perform. Wherever you live, at home or outside home, just keep a picture of Śrī Caitanya Mahāprabhu and chant Hare Kṛṣṇa mantra before Him. Then your life will be successful.
