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

Lord's so-called "birth" is not in reality a change of condition for Him. In the Puruṣa-sūkta prayer it is said: ajāyamāno bahudhā vijāyate "Although He is never born, the Lord takes birth again and again in many different forms." Therefore the word "birth" here means "the appearance of the Supreme Lord, who never really takes birth." The word "ca" (also) in this sūtra means, "also because He is the reservoir of transcendental mellows." This is confirmed in the Taittirīya Upaniṣad (2.7.1): raso vai saḥ "The Supreme Personality of Godhead is the reservoir of transcendental mellows."* By His inconceivable potency, the Supreme Lord appears in a particular form appropriate to the mellows and pastimes His devotees desire. This is perfectly proper. The Lord has numberless devotees, beginning with the liberated souls. This is described in the Ṛg Veda (1.22.20): tad viṣṇoḥ paramaṁ padaṁ sadā paśyanti sūrayaḥ "The wise and learned devotees always see the supreme abode of Lord Viṣṇu."* The Supreme Lord, who is always one, simultaneously appears in His different ages before His different devotees. Something similar is seen in Bṛhad-āraṇyaka Upaniṣad (5.2.1-3), where the syllable "da" was interpreted in three ways by the demigods, human beings, and demons. In this way, because the Supreme Lord is all-pervading and because the Lord always remains one, one should certainly meditate on the Lord's pastimes of childhood and other ages.
