“ ‘O my Lord! Transcendental poets and experts in spiritual science could not fully express their indebtedness to You, even if they were endowed with the prolonged lifetime of Brahmā, for You appear in two features — externally as the ācārya and internally as the Supersoul — to deliver the embodied living being by directing him how to come to You.’
Purport
This is a verse from Śrīmad-Bhāgavatam (11.29.6). It was spoken by Uddhava after he had been instructed in yoga by Śrī Kṛṣṇa.
