Chapter XIV · Śloka 8
तमस्त्वज्ञानजं विद्धि मोहनं सर्वदेहिनाम् ।
प्रमादालस्यनिद्राभिस्तन्निबध्नाति भारत ॥
tamas tv ajñāna-jaṃ viddhi mohanaṃ sarva-dehinām |
pramādālasya-nidrābhis tan nibadhnāti bhārata ||
But know tamas to be born of ignorance, deluding all embodied beings; it binds, O Bhārata, through negligence, laziness, and sleep.
Tamas arises from ignorance and smothers the light of discernment; it binds the soul in the dullness of delusion, heedlessness, and torpor.
