Śrīmad-Bhāgavatam · Text 3.12.19
Who is speaking and story frame
तपसैव परं ज्योतिर्भगवन्तमधोक्षजम् ।
सर्वभूतगुहावासमञ्जसा विन्दते पुमान् ॥ १९ ॥
tapasaiva paraṁ jyotir
bhagavantam adhokṣajam
sarva-bhūta-guhāvāsam
añjasā vindate pumān
By penance only can one even approach the Personality of Godhead, who is within the heart of every living entity and at the same time beyond the reach of all senses.
