Bṛhad-bhāgavatāmṛta Part 2 Chapter 2 Text 119

kadācit sanakādīṁś ca
dhyāna-niṣṭhā-vaśaṁ gatān
vindatas tāni rūpāṇi
dṛṣṭvāpnomi parāṁ mudamTRANSLATION
Sometimes when Sanaka and his brothers were absorbed in meditation they would assume those forms of the Lord. Seeing this, I would relish extreme pleasure.
