Kṛṣṇa says that, "My devotee, when he offers Me something eatable, with faith, love and devotion, I eat." Then is He speaking lies? No. He eats. But the atheist class of men, they do not know. They see that the plate is full. Sometimes, if He's forced, He can eat also; there are some incidences. Anyway, He, simply by seeing, He can eat. Simply by seeing. If you don't believe that He's not eating . . . but from the Vedic injunction we can understand that you put the food plate before the Lord, and Lord is seeing, and that is His eating. He's not hungry, but He can eat the whole universe at a time. This is God's position. He can devour the whole universe, as you have seen the virāṭ-rūpa.
So this yajña performance required fire. Tasmād agnis trayīmayaḥ. Trayīmaya. Trayī means Vedas. There are three departments of Vedas; therefore it is called trayī. Trayī means three: karma-kāṇḍa, jñāna-kāṇḍa and upāsanā-kāṇḍa. So in karma-kāṇḍa platform, fruitive activities, the sacrifice is required, and for sacrificing you require fire, so that you can gradually understand what is the Absolute Truth. Similarly, if you want to see Brahman, the Supreme Absolute Truth, then you have to come to the platform of goodness. You cannot remain on the platform of ignorance and passion.
Therefore our training to the student is to bring him to the platform of goodness, brāhmin. Brahmā jānātīti brāhmaṇaḥ. Brahmā-darśana. Brahmā-darśana means one who has seen brahma, or one who has known brahma. He's called brāhmin. Brāhmin is not that being born in the family of a brahmin and having a sacred thread, two-cent worth. No. Brāhmin means one who has seen, brahma-darśana. Darśana means seeing. So, in order to see the Absolute Truth, one has to come to the platform of goodness. Tamasas tu rajas tasmāt sattvaṁ yad brahma-darśanam. Yad sattvam, the platform which is called goodness. And in that platform you can see God, or you can realize what is Absolute Truth.
So the so-called scientist, they are trying to find out the ultimate source of everything, the Absolute Truth. But because they are not on the platform of goodness, how they can see? They cannot see. The Absolute Truth is coming before us, in person, and is showing His activity as Absolute Truth, and big, big ācāryas, they're accepting Him, the Absolute Truth. Still, these rascals, they cannot see. The so-called scientists, rascals, they cannot see—because they're not on the platform of goodness. They're in the platform of ignorance. Therefore they . . .
Even . . . just like Kṛṣṇa, when He appeared on this planet, there were so many millions of people. But very few of them could understand that He was the Supreme Personality of Godhead—only the inhabitants of Vṛndāvana and the Pāṇḍavas and some others. Not that all of them. Because all of them cannot understand. Manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye (BG 7.3). Out of many millions of person, kaścit, somebody is trying to become a brahmin. That is siddhaye. Kaścid yatati siddhaye. Siddhaye means to become successful. And yatatām api siddhānām (BG 7.3). And out of many millions of person who has become successful, out of them, some may know what is Kṛṣṇa.
