paramāṇu-maye cittaḿ
bhūtānāḿ mayi rañjayan
kāla-sūkṣmārthatāḿ yogī
laghimānam avāpnuyāt
parama-anu-maye -- in the form of atoms; cittam -- his consciousness; bhutanam -- of the material elements; mayi -- in Me; ranjayan -- attaching; kala -- of time; sukshma -- subtle; arthatam -- being the substance; yogi -- the yogi; laghimanam -- the mystic perfection laghima; avapnuyat -- may obtain.
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.
