Prabhupada's lecture - Śrīmad-Bhāgavatam 1.3.16 and Initiation - Los Angeles, September 21, 1972
Just like if you speak to an ant or what is called, insect... There are many insects. They take their birth... We have seen it. In India we see. In this season there are insects. They are called divāli-pokā, insect divāli. Just in the evening they are born. And they flock together before a light, (sound imitation:) bawnh, bawnh, bawnh, bawnh, like that. And throughout the whole night they will do, and at the end of the night, in the morning, you will see, they are, in heap, they are lying dead. So their life, the duration of life is that night. within that night they take their birth, they grow, they beget children, family, and defend, eat, mate. Everything is complete within the night. And at the end of the night, it is finished. So similarly, if to these flies, if you say, "Oh, we are dying like this, but there is human being. This is only one night. And such...
There is another day also of the same period. Then together, day and night, such thirty day and night makes their month. And such 12 months make their year. And such hundred years they live." So how the fly will understand? Similarly, we cannot understand. When the duration of life of Brahmā is described, we think it is story. Similarly, they will think also story. Nothing is story. In the Vedic literatures all informations are there. Their relative life, big and small, smaller than the smallest, bigger than the biggest. Don't think that these description in the Vedas, they are stories. They are not stories. They are facts. But we cannot accommodate in our poor teeny brain. That's all.
