paramanu-maye cittam

 bhutanam mayi rañjayan

kala-suksmarthatam yogi

 laghimanam avapnuyat

 

Translation: 

 

I exist within everything, and I am therefore the essence of the atomic constituents of material elements. By attaching his mind to Me in this form, the yogi may achieve the perfection called laghima, by which he realizes the subtle atomic substance of time.

 

Purport: 

 

Srimad-Bhagavatam elaborately explains that kala, or time, is the transcendental form of the Lord that moves the material world. Since the five gross elements are composed of atoms, the atomic particles are the subtle substance or manifestation of the movements of time. More subtle than time is the Personality of Godhead Himself, who expands His potency as the time factor. By understanding all these things clearly the yogi obtains laghima-siddhi, or the power to make himself lighter than the lightest.
