CC Madhya 24.201

jīvera svabhāva — kṛṣṇa-‘dāsa’-abhimāna
dehe ātma-jñāne ācchādita sei ‘jñāna’
Synonyms: 
jīvera svabhāva — the original characteristic of all living entities; kṛṣṇa-dāsa — servant of Kṛṣṇa; abhimāna — the conception; dehe — in the material body; ātma-jñāne — by the conception of the self; ācchādita — covered; sei jñāna — that original consciousness.
Translation: 
“The original nature of every living entity is to consider himself the eternal servant of Kṛṣṇa. But under the influence of māyā he thinks himself to be the body, and thus his original consciousness is covered.
