Śrīpāda Śaṅkarācārya avoided to write any comments on Śrīmad-Bhāgavatam. He has written comments on Bhagavad-gītā, but he has completely avoided to write any comment on Bhāgavata because he knew that "I am doing the wrong thing. How can I touch Śrīmad-Bhāgavatam?" Śrīmad-bhāgavatam amalaṁ purāṇaṁ yad vaiṣṇavānāṁ priyam (SB 12.13.18). He has purposefully avoided. And the ācārya, other ācāryas like Śrī Rāmānujācārya, Madhvācārya, Viṣṇu Svāmī and up to Caitanya Mahāprabhu, everyone has accepted, śrīmad-bhāgavatam amalaṁ purāṇam.
Amalam means there is no material contamination; pure description. Therefore Vyāsadeva, from the very beginning he says that dharmaḥ projjhita-kaitavo 'tra paramo nirmatsarāṇām (SB 1.1.2): "This book is not meant for the person who is envious." Envious . . . You begin enviousness from Kṛṣṇa. Kṛṣṇa says, sarva dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). The envious person will say, "Oh, this is too much. Why shall I surrender to Kṛṣṇa? I am also Kṛṣṇa. I am also God. This is too much." This is rascaldom. The actual fact is that we are eternal servant of Kṛṣṇa, we have forgotten it, and therefore we have become servant of māyā. We are suffering, and Kṛṣṇa, out of His kindness, He comes to prove that the living entities are eternal servant and He is the eternal master. Still, because they are contaminated, contaminated by the yogamāyā . . . contaminated by māyā, mahāmāyā . . . Mahāmāyā. Yā devī sarva-bhūteṣu nidrā-rūpeṇa saṁśritā. Mahāmāyā. This material energy is described in the Chandi(?), yā devī sarva-bhūteṣu nidrā-rūpeṇa saṁśritā. (S)he's keeping everyone in sleeping, more dozes. Utthiṣṭhata jāgrata prāpta varān nibodhata (Kaṭha Upaniṣad 1.3.14). And therefore Veda says that "Don't sleep. Get up, rascal. Get up. This is the opportunity." But no. Yogamāyā-samāvṛtaḥ. Yogamāyā is keeping him in sleeping condition. Nidrālasya. So we should be very careful.
