tvam adir anto bhuvanasya madhyam
ananta-saktim purusam yam ahuh
kalo bhavan aksipatisa visvam
sroto yathantah patitam gabhiram
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O my Lord, You are the beginning, the manifestation and the ultimate dissolution of the three worlds, and You are celebrated in the Vedas as the reservoir of unlimited potencies, the Supreme Person. O my Lord, as waves attract branches and leaves that have fallen into deep water, You, the supreme eternal time factor, attract everything in this universe.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The time factor is sometimes described as kala-srota, waves of time. Everything in this material world is within the time factor and is being carried away by waves of attraction, which represent the Supreme Personality of Godhead.
