गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

sthāna-viśeṣāt prakāśādi-vat sthāna—of places; viśeṣāt—from the variety; prakāśa—light; ādi—beginning with; vat—like. Like light and other things, so He also is different in different places. Purport by Śrīla Baladeva Vidyābhūṣaṇa Although the Supreme Personality of Godhead is one, nevertheless, in different places and before different devotees He manifests different kinds of opulence, power, and sweetness. In this way, in the presence of devotees in the various mellows, such as the mellows of peacefulness, servitude, and friendship, the Lord manifests many different kinds of forms. He does this in the same way as light or other things also manifest many different kinds of forms. As the light of a lamp appears clear or red when reflected from crystals or rubies set in a temple's walls, and as sound, although originally one, appears different when sounded by a conchshell, mṛdaṅga, flute, or other musical instrument, so the Supreme Personality of Godhead manifest sweetness and other attributes according to the different circumstances. That is the meaning. When the Lord manifests His great opulence, He is worshiped by the rules and regulations of vidhi-bhakti. That manifestation is compared to the light reflected from crystal. When the Lord manifests His great sweetness, He is worshiped by the spontaneous love of ruci- bhakti. That manifestation is compared to the light reflected from rubies. In this way the Lord's many manifestations in different abodes and in relation to the different kinds of devotion of different kinds of devotees, are basically of these two kinds (opulence and sweetness). Sūtra 36 upapateś ca upapateḥ—because of reasonableness; ca—also. Also because it is reasonable. Purport by Śrīla Baladeva Vidyābhūṣaṇa
