Translation
(I am just left away by Him) Whose separation by a moment would render all the universes certainly as unfavourable void as it were these bodies would be called corpses only when the living force is away from them.
Purport
Factually for a living being there is no one dearer than the Lord. The Lord expands Himself by innumerable parts and parcels as Samsa and Bibhinansa. Paramatma is the Samsa Part of the Lord whereas the Bibhinansa parts are the living beings. As the living being is the important factor in the material body or without the living being material body has no value similarly without Paramatma the living being has no statusqua. Similarly—Brahman or Paramatman has no locus standi without the Supreme Lord Sri Krishna. These things are thoroughly explained in the Bhagwat Geeta (B.G. 15/18) They are all interlinked with one another or interdependent factors, as such at the ultimate issue the Lord is the Summum Bonum and therefore the vital principle of everything.
