That by which dreams, fear, sorrow, dejection, and even intoxication
Are not cast off, that dull-witted resolve, O Partha, is taamasic.

Resolve by which a dull person does not give up sleep, fear, grief, despair, and arrogance; that resolve is Taamasika, O Arjuna.

Source: The Bhagavad-Gita: The Sacred Song

And that determination which cannot go beyond dreaming, fearfulness, lamentation, moroseness, and illusion--such unintelligent determination is in the mode of darkness.
