Srila Visvanatha Cakravarti Thakura points out that just as a lamp does not seem to shine as brightly in sunlight as it does in the shade, or as a diamond does not seem as brilliant on a silver platter as it does on a plate of blue glass, the Lord's pastimes as Govinda do not seem as amazing in the transcendental abode of Vaikuntha as they do within the material realm of Maya. Lord Krishna comes to the earth and acts toward His pure devotees exactly like a devoted son, boyfriend, husband, father, friend and so on, and within the darkness of material existence these brilliant, liberated pastimes give unlimited ecstasy to the surrendered devotees of the Lord.
In his Krishna, the Supreme Personality of Godhead, Srila Prabhupada quotes Lord Brahma as follows: "I can also understand that Your appearance as a small cowherd boy, a child of the cowherd men, is not at all a material activity. You are so much obliged by their affection that You are here to enthuse them with more loving service by Your transcendental presence. "
