The type of “understanding” which brings sorrow to everyone including the individual himself, is the “understanding” of the ‘dull’ (Tamasic). Actually it is no “understanding” at all; it can, at best, be called only a chronic bundle of misunderstandings. Such an intellect runs into its own conclusions, but unfortunately, it always lands up with wrong conclusions only. It has such a totally perverted “understanding” that it recognises “A-dharma” as “Dharma,” the ‘right’ as ‘wrong.’ This faculty of coming to wrong judgements is amply seen in the dull, because their entire reasoning capacity is enveloped by complete darkness and egoistic drunkenness.

DISCUSSING THE THREE TYPES OF “FORTITUDE,” LORD KRISHNA CONTINUES:

O Partha, sa, that; buddhih, intellect; tamasi, is born of tamas; ya, which; tamasavrta, being covered by darkness; manyate, considers, understands; adharmam, vice, what is prohibited; iti, as; dharmam, virtue, what is prescribed; and ca, verily; perceives sarvarthan, all things, all objects of knowledge without exception; viparitan, contrary to what they are.
