'anghri-padma-sudha'ya kahe 'krsna-sangananda'
vidhi-marge na paiye vraje krsna-candra
anghri-padma-sudhaya—by the nectar derived from the lotus feet of Krsna; kahe—it says; krsna-sanga-ananda—transcendental bliss by the association of Krsna; vidhi-marge—on the path of regulative principles; na paiye—one does not get; vraje—in Goloka Vrndavana; krsna-candra—Lord Krsna.
"The word 'anghri-padma-sudha' means 'associating intimately with Krsna.' One can attain such perfection only by spontaneous love of God. One cannot obtain Krsna in Goloka Vrndavana simply by serving the Lord according to regulative principles.
