यया स्वप्नं भयं शोकं विषादं मदमेव च न विमुञ्चति दुर्मेधा धृतिः सा पार्थ तामसी ॥ 18.35 ॥
yayā svapnaṃ bhayaṃ śokaṃ viṣādaṃ madameva ca na vimuñcati durmedhā dhṛtiḥ sā pārtha tāmasī
Translation
"O Partha, the resolve by which a foolish person does not let go of sleep, fear, grief, despondency and intoxication (mada) — that is tamasic resolve."
