Everyone is servant. You do not . . . you, you can perform yajña for ordinarily, but if you keeps . . . if you be simply under the shelter of Kṛṣṇa, you do not require to perform different demigod yajñas, deva-yajña. That is not required. The example is given that if you pour water in the root of the tree, you do not require to pour water in the branches, in the twigs, in the flowers, in the fruits. It is automatically done. If you supply food to the stomach, then you do not require to feed the eyes, hands, legs, separately. There is no need; neither it is possible to give separate, I mean to say, food, materials for nourishing the different parts of the body. One place is sufficient. Similarly, if we worship Kṛṣṇa, the source of everything, the root of everything . . . aham ādir hi yajñānām . . . devānām. Deva-yajña.
So Kṛṣṇa says that you don't require to perform different yajñas. That is not possible in this age especially. It requires large amount of wealth to perform such yajñas. Nowadays people are suffering for want of sufficient food grains, and in the yajña tons and thousands of mounds of food grains are offered in the fire. That is good. But there is no food grains, there is no ghee. That is not possible in this age. Therefore yajña is not possible. The . . . you can perform very easily the saṅkīrtana-yajña. Then everything will be performed. Yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ (SB 11.5.32). Those who are intelligent person, they can perform yajña, saṅkīrtana-yajña.
This is recommended in this age. Other yajñas is not possible. Kṛte yad dhyāyato viṣṇuṁ tretāyāṁ yajato makhaiḥ (SB 12.3.52). Tretāyām. Yajña performance was very prominent in the Tretā-yuga, at that time. But at present moment it is not possible. Dhyāna-yajña, dravya-yajña, jñāna-yajña and saṅkīrtana-yajña. So in this age, saṅkīrtana-yajña is recommended. Yajñaiḥ saṅkīrtana-prāyair yajanti hi sumedhasaḥ (SB 11.5.32). Sumedhasaḥ means those who have got good brain. And it is so easy, anywhere you can perform. Any part of the world, you assemble together. Saṅkīrtana means bahubhir militvā (quoted in Śrī Amnāya-sūtra 62), by intermingling various persons. Just like we are doing here saṅkīrtana—kīrtana and saṅkīrtana. Kīrtana means alone, and saṅkīrtana means in the assembly of many others. That is called saṅkīrtana. So that is recommended, that many persons, you sit together. There is no need of even instrument, but because Lord Caitanya introduced this khol, karatāla; otherwise this clapping is sufficient.
So it is very easy, saṅkīrtana-yajña. You sit down familywise, all the family members. If you perform saṅkīrtana, Hare Kṛṣṇa mahā-mantra, with the clapping of hands, that is saṅkīrtana-yajña, very easy to perform. But people will not do that. Instead of performing saṅkīrtana-yajña in the evening to become free from all fears of life, they will go to the restaurant, to the cinema and other places, talking unnecessarily in clubs, societies, waste their time. This is going on. This is modern education. This is modern civilization. They are not aware of the tīvraṁ bhayam, the most fierceful situation of birth, death, old age and disease. This is the opportunity, the human life, how to get out of it. The means are there. But we are so fools, we are so foolishly educated in the name of modern civilization, that we neglect all these things and we place ourself in the waves of the material nature. Māyār bośe, jāccho bhese', khāccho hābuḍubu bhāi. We are being carried away by the waves of this material nature, and we have submitted to the laws of material nature. And therefore we are subjected to birth, death, old age and disease. And not only birth—there is no guarantee what kind of birth next life.
