Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 56

Sanskrit:

कालिय उवाचवयं खला: सहोत्पत्त्या तामसा दीर्घमन्यव: ।स्वभावो दुस्त्यजो नाथ लोकानां यदसद्ग्रह: ॥ ५६ ॥

ITRANS:

kāliya uvācavayaṁ khalāḥ sahotpattyātamasā dīrgha-manyavaḥsvabhāvo dustyajo nāthalokānāṁ yad asad-grahaḥ

Translation:

The serpent Kāliya said: Our very birth as a snake has made us envious, ignorant and constantly angry. O my Lord, it is so difficult for people to give up their conditioned nature, by which they identify with that which is unreal.

Purport:

Śrīla Sanātana Gosvāmī points out that because of his wretched condition, Kāliya was unable to compose original prayers to the Lord, and thus he paraphrased some of the prayers offered by his wives. The word asad-graha indicates that a conditioned soul seizes upon impermanent and impure things such as his own body, the bodies of others, and other countless varieties of material sense objects. The ultimate result of such material attachment is frustration, disappointment and anguish — a fact that has now become crystal clear to the poor serpent Kāliya.
