A conditioned soul, as we are, under the condition of the material nature, three modes of material nature, how our knowledge can be perfect? It is not possible. The first defect is, because we are conditioned, we commit mistake, so many. And we become illusioned. Just like every knowledge is being based on the illusion that, "I am this body, material body," which I am not. But the whole world is going on under this conception that, "I am this body." "I am American," "I am Indian," "I am brāhmin," like that.
So the basic principle is illusion. And there are so many mistakes we commit. And the senses are imperfect. And although my senses are imperfect, I, still, I theorize, "It may be . . ." "It is like this," "It is like that." These are all imperfect things. Therefore whatever knowledge we may make progress, it is saṁśayam; it remains doubt, uncertainty.
But what Kṛṣṇa says, you can test even with your experimental knowledge. That is Vedic knowledge. Vedic knowledge, it is not dogma. The . . . the statement is there after sufficient experiment. So if we accept Vedic knowledge, we save so much time. We may go on experimenting with our limited power of senses, but that will always remain doubtful. But if we accept Vedic knowledge, apauruṣa knowledge, then it is perfect.
Asaṁśayaṁ samagram. This samagram, this word, is very significant. Samagram means "complete." To understand Kṛṣṇa means to understand the whole cosmic manifestation, God, the material nature, the time factor, the living entities, their respective relationship, everything. That is called samagram. Not that a Kṛṣṇa conscious person does not know about the creation of the material manifestation. He knows, by his reason.
