Translation: 
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: 

The time factor is sometimes described as kāla-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.
