18.32 That intellect which is shrouded in darkness, imagining irreligion to be religion, and perceiving untruth to be the truth, is of the nature of ignorance, O Parth.
The tāmasic intellect is without the illumination of sublime knowledge. Hence, it misconstrues adharma to be dharma . For example, a drunk is attached to the inebriation that drinking alcohol provides. Hence, his poor intellect, covered with the fog of darkness, cannot even perceive the sheer ruin that he brings onto himself, and he does not even mind selling his property to get his next bottle. In the tāmasic intellect, the faculty of judgment and the ability for logical reasoning become lost.
