pūrṇaiśvarye śrī-catur-vyūha-madhye
rūpaṁ yasyodbhāti saṅkarṣaṇākhyaṁ
taṁ śrī-nityānanda-rāmaṁ prapadye
māyā-atīte-beyond the material creation; vyāpi-all-expanding; vaikuṇṭha-loke-in Vaikuṇṭhaloka, the spiritual world; pūrṇa-aiśvarye-endowed with full opulence; śrī-catuḥ-vyūha-madhye-in the quadruple expansions (Vāsudeva, Saṅkarṣaṇa, Pradyumna and Aniruddha); rūpam-form; yasya-whose; udbhāti-appears; saṅkarṣaṇa-ākhyam-known as Saṅkarṣaṇa; tam-to Him; śrī-nityānanda-rāmam-to Lord Balarāma in the form of Lord Nityānanda; prapadye-I surrender.
I surrender unto the lotus feet of Śrī Nityānanda Rāma, who is known as Saṅkarṣaṇa in the midst of the catur-vyūha [consisting of Vāsudeva, Saṅkarṣaṇa, Pradyumna and Aniruddha]. He possesses full opulences and resides in Vaikuṇṭhaloka, far beyond the material creation.
This is a verse from Śrī Svarūpa Dāmodara Gosvāmī's diary. It appears as the eighth of the first fourteen verses of Śrī Caitanya-caritāmṛta.
