Śrīmad-Bhāgavatam · Text 12.6.29
Who is speaking and story frame
सैषा विष्णोर्महामायाबाध्ययालक्षणा यया ।
मुह्यन्त्यस्यैवात्मभूता भूतेषु गुणवृत्तिभि: ॥ २९ ॥
saiṣā viṣṇor mahā-māyā-
bādhyayālakṣaṇā yayā
muhyanty asyaivātma-bhūtā
bhūteṣu guṇa-vṛttibhiḥ
This is indeed the Supreme Lord Viṣṇu’s illusory energy, which is unstoppable and difficult to perceive. Although the individual spirit souls are part and parcel of the Lord, through the influence of this illusory energy they are bewildered by their identification with various material bodies.
