।।14.13।।हे कुरुनन्दन तमोगुणके बढ़नेपर अप्रकाश? अप्रवृत्ति? प्रमाद और मोह -- ये वृत्तियाँ भी पैदा होती हैं।


Rudra Vaishnava Sampradaya - Commentary




Lord Krishna confirms that tama guna or mode of  ignorance  is  darkness  of
knowledge,   absence    of    discrimination,    indolence,    listlessness,
forgetfulness, delusion, erroneous conclusions. Where  such  characteristics
are seen it is clear  that  tama  guna  is  predominant  within  a  jiva  or
embodied being.


Brahma Vaishnava Sampradaya - Commentary



Shri Vaishnava Sampradaya - Commentary

Here Lord Krishna explains what is indicative of tama guna or  the  mode  of
ignorance.
The word aprakasa means devoid of illumination, nescience, ignorance.
The word apravrrtih means inertia, lethargy, absence of effort.
The  word  pramada  means  madness,  fragmentation,  propensity  for  sinful
activities.
The word moha means illusion, distortion, misinterpretation of reality.
When tamas is predominant then  delusion  and  perversion  are  seen  to  be
rampant in society.
