tvāṁ bījam ātmani tataṁ sa bahir vicintya
nāvindad abda-śatam apsu nimajjamāno
jāte ’ṅkure katham uhopalabheta bījam
This is the description of the cosmic manifestation. The development of the cosmic manifestation is like the fructification of a seed. When cotton is transformed into thread, the cotton is no longer visible, and when the thread is woven into cloth, the thread is no longer visible. Similarly, it is perfectly correct that when the seed that had generated from the navel of Garbhodakaśāyī Viṣṇu became manifested as the cosmic creation, one could no longer understand where the cause of the cosmic manifestation is. Modern scientists have tried to explain the origin of creation by a chunk theory, but no one can explain how such a chunk might have burst. The Vedic literature, however, explains clearly that the total material energy was agitated by the three modes of material nature because of the glance of the Supreme Lord. In other words, in terms of the chunk theory, the bursting of the chunk was caused by the Supreme Personality of Godhead. Thus one must accept the supreme cause, Lord Viṣṇu, as the cause of all causes.
