तत्कर्म यन्न बन्धाय सा विद्या या विमुक्तये ।
आयासायापरं कर्म विद्यान्या शिल्पनैपुणम् ॥
tat karma yan na bandhāya sā vidyā yā vimuktaye |
āyāsāyāparaṁ karma vidyānyā śilpa-naipuṇam ||
(Viṣṇu Purāṇa: 1.19.41)
“[Prahlāda Mahārāja to Hiraṇyakaśipu:] Action is that which does not lead to bondage. Knowledge is that which leads to liberation [from bondage]. Action otherwise leads to hardship, and knowledge otherwise is [mere] proficiency in a craft.”
