Śrīmad-Bhāgavatam · Text 11.14.20
Who is speaking and story frame
न साधयति मां योगो न साङ्ख्यं धर्म उद्धव ।
न स्वाध्यायस्तपस्त्यागो यथा भक्तिर्ममोर्जिता ॥ २० ॥
na sādhayati māṁ yogo
na sāṅkhyaṁ dharma uddhava
na svādhyāyas tapas tyāgo
yathā bhaktir mamorjitā
My dear Uddhava, the unalloyed devotional service rendered to Me by My devotees brings Me under their control. I cannot be thus controlled by those engaged in mystic yoga, Sāṅkhya philosophy, pious work, Vedic study, austerity or renunciation.
Read the purport on Vedabase.ioFrom Canto 10, chapter 14 onward, the translation and purports were completed by Śrīla Prabhupāda's disciples after his departure, and published by the Bhaktivedanta Book Trust.
