So therefore in the Vedic culture the karma-kāṇḍīya-yajña is recommended. At least, you get a better body. Don't go to the lower body. Ūrdhvaṁ gacchanti sattva-sthāḥ (BG 14.18). Better body in higher planetary system. That is karma-kāṇḍīya-vicāra. Therefore yajña. Yajñāyācarataḥ karma. Everything should be easier. Yajña-śiṣṭāśinaḥ santo mucyante sarva-kilbiṣaiḥ. The same thing.
Just like here. We are performing yajña, the saṅkīrtana-yajña. We are preparing food for Kṛṣṇa. That is yajña. And when we eat the remnants of foodstuff, that is also yajña-śiṣṭāśinaḥ, remnants of foodstuff. Yajña-śiṣṭāśinaḥ santaḥ. Aśina. Aśina means eating. After offering in the yajña, if you eat, yajña-śiṣṭāśinaḥ santaḥ, you become a santaḥ, saintly person. And yajña-śiṣṭāśinaḥ, mucyante sarva-kilbiṣaiḥ. He becomes free from all sinful reaction.
And bhuñjate te tv aghaṁ pāpā ye pacanty ātma-kāraṇāt (BG 3.13). And who is cooking for himself very palatable dishes, he is bhuñjate te tv aghaṁ pāpā. He is simply eating sins, and he has to suffer. Therefore we have to eat, we have to work, we have to do everything only for yajñāya, not for any other purpose. Then we are entangled. As soon as we do anything for my sense gratification, then we are entangled immediately, goodness or badness, goodness, passion, or ignorance. So there are very complicated laws, but we do not know. That is ignorance. So we have to know what are these complicated laws. That is called jñānāvasthita-cetasaḥ. Ignorant person, they suffer from disease, they suffer from legal action, because ignorant.
