Bhagavad-gītā As It Is · Text 14.8
How goodness, passion and ignorance bind
तमस्त्वज्ञानजं विद्धि मोहनं सर्वदेहिनाम् ।
प्रमादालस्यनिद्राभिस्तन्निबध्नाति भारत ॥ ८ ॥
tamas tv ajñāna-jaṁ viddhi
mohanaṁ sarva-dehinām
pramādālasya-nidrābhis
tan nibadhnāti bhārata
O son of Bharata, know that the mode of darkness, born of ignorance, is the delusion of all embodied living entities. The results of this mode are madness, indolence and sleep, which bind the conditioned soul.
