Srimad Bhagavatam 11.14.14
Krishna to Uddhavaन पारमेष्ठ्यं न महेन्द्रधिष्ण्यंन सार्वभौमं न रसाधिपत्यम् ।न योगसिद्धीरपुनर्भवं वामय्यर्पितात्मेच्छति मद्विनान्यत् ॥
Transliteration
na pārameṣṭhyaṃ na mahendradhiṣṇyaṃna sārvabhaumaṃ na rasādhipatyamna yogasiddhīrapunarbhavaṃ vāmayyarpitātmecchati madvinānyat
One who has offered the self to me desires nothing apart from me: neither Brahma’s station nor Indra’s seat, neither earthly empire nor rule of the lower realms, neither powers of yoga nor freedom from rebirth.
Original King of Dwarka translationReflection inspired by Srimad Bhagavatam 11.14.14
The imagined rewards grow larger, yet each is set aside. Devotion here is not a transaction made more impressive by the size of its return.
Source & context
Krishna describes devotion that does not seek him as a means to another reward. The following verse addresses Uddhava’s exceptional dearness; that is a distinct verse.
