Śrīmad-Bhāgavatam · Text 11.28.29
Who is speaking and story frame
कुयोगिनो ये विहितान्तरायै-
र्मनुष्यभूतैस्त्रिदशोपसृष्टै: ।
ते प्राक्तनाभ्यासबलेन भूयो
युञ्जन्ति योगं न तु कर्मतन्त्रम् ॥ २९ ॥
kuyogino ye vihitāntarāyair
manuṣya-bhūtais tridaśopasṛṣṭaiḥ
te prāktanābhyāsa-balena bhūyo
yuñjanti yogaṁ na tu karma-tantram
Sometimes the progress of imperfect transcendentalists is checked by attachment to family members, disciples or others, who are sent by envious demigods for that purpose. But on the strength of their accumulated advancement, such imperfect transcendentalists will resume their practice of yoga in the next life. They will never again be trapped in the network of fruitive work.
