Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 30

Sanskrit:

भूतै: पञ्चभिरारब्धे देहे देह्यबुधोऽसकृत् ।अहंममेत्यसद्ग्राह: करोति कुमतिर्मतिम् ॥ ३० ॥

ITRANS:

bhūtaiḥ pañcabhir ārabdhedehe dehy abudho ’sakṛtahaṁ mamety asad-grāhaḥkaroti kumatir matim

Translation:

By such ignorance the living entity accepts the material body, which is made of five elements, as himself. With this misunderstanding, he accepts nonpermanent things as his own and increases his ignorance in the darkest region.

Purport:

The expansion of ignorance is explained in this verse. The first ignorance is to identify one’s material body, which is made of five elements, as the self, and the second is to accept something as one’s own due to a bodily connection. In this way, ignorance expands. The living entity is eternal, but because of his accepting nonpermanent things, misidentifying his interest, he is put into ignorance, and therefore he suffers material pangs.
