yam āmananti sma hi śabda-yoniṁ
api — as also; svit — whether; āste — does He; bhagavān — the Personality of Godhead; sukham — all happiness; vaḥ — of you; yaḥ — one who; sātvatām — of the devotees; kāma-dughaḥ — source of all desires; aniruddhaḥ — the plenary expansion Aniruddha; yam — whom; āmananti — they accept; sma — from yore; hi — certainly; śabda-yonim — the cause of the Ṛg Veda; manaḥ-mayam — creator of the mind; sattva — transcendental; turīya — the fourth expansion; tattvam — principle.
May I inquire whether Aniruddha is doing well? He is the fulfiller of all the desires of the pure devotees and has been considered from yore to be the cause of the Ṛg Veda, the creator of the mind and the fourth plenary expansion of Viṣṇu.
Ādi-caturbhuja, the original expansions from Baladeva, are Vāsudeva, Saṅkarṣaṇa, Pradyumna and Aniruddha. All of Them are viṣṇu-tattvas, or nondifferent Personalities of Godhead. In the incarnation of Śrī Rāma, all these different expansions appeared for particular pastimes. Lord Rāma is the original Vāsudeva, and His brothers were Saṅkarṣaṇa, Pradyumna and Aniruddha. Aniruddha is also the cause of Mahā-Viṣṇu, from whose breathing the Ṛg Veda appeared. All this is nicely explained in the Mārkaṇḍeya Purāṇa. In the incarnation of Lord Kṛṣṇa, Aniruddha appeared as the son of the Lord. Lord Kṛṣṇa in Dvārakā is the Vāsudeva expansion of the original group. The original Lord Kṛṣṇa never leaves Goloka Vṛndāvana. All the plenary expansions are one and the same viṣṇu-tattva, and there is no difference in Their potency.
