O Muni, in the last millennium I was born as the son of a certain maidservant engaged in the service of brāhmaṇas who were following the principles of Vedānta. When they were living together during the four months of the rainy season, I was engaged in their personal service.

मूल श्लोकः
अहं पुरातीतभवेऽभवं मुने दास्यास्तु कस्याश्चन वेदवादिनाम् । निरूपितो बालक एव योगिनां शुश्रूषणे प्रावृषि निर्विविक्षताम्
ahaṃ purātītabhave'bhavaṃ mune dāsyāstu kasyāścana vedavādinām | nirūpito bālaka eva yogināṃ śuśrūṣaṇe prāvṛṣi nirvivikṣatām
