अप्रकाशः अप्रवृत्तिः च प्रमादो मोह एव च ।
तमस्येतानि जायन्ते विवृद्धे कुरुनन्दन ॥ १३ ॥

aprakAzaH apravRttiH ca pramAdo moha eva ca |
tamasyetAni jAyante vivRddhe kurunandana || 13 ||

कुरुनन्दन [kurunandana] Arjuna, अप्रकाशः [aprakAzaH] being ignorant of the true nature of things, अप्रवृत्तिः [apravRttiH] reluctance to do anything, प्रमादः [pramAdaH] mistakes, मोह च [moha ca] and delusion - एतनि [etani] these behaviors जायन्ते [jAyante] arise विवृद्धे तमसि [vivRddhe tamasi] in tamas , when this quality predominates the others.

‘Being ignorant of the true nature of things’ happens in the absence of awareness.

‘Reluctance to do anything’ is being pretentious and stiff.

‘Mistakes’ happen when we do work that must not be done, when we are unmindful of the consequences of such work.

‘Delusion’ is false knowledge.

Such behavior comes from a dominant tamas . Recognize the predominance of tamas when they are observed.
