BG 14.13

When there is an increase in the mode of ignorance, O son of Kuru, darkness, inertia, madness and illusion are manifested.

14.13. Absence of [mental] illumination, non-excertion, negligence and mere delusion-these are born when the Tamas is on the increase predominantly, O darling of the Kurus !

14.13 Darkness, stagnation, folly and infatuation are the result of the dominance of Ignorance, O joy of the Kuru-clan!

14.11-13 Sarva-etc. upto kurunandana. In all the gates : in all the sense-organs. Greed etc., are born in succession when the Rajas dominates. Similarly, absence of mental illumination and so on arise in succession only at the time of the increase of the Tamas.

14.13 'Non-illumination' is the absence of knowledge. 'Inactivity' is immovableness. 'Negligence' is inadvertence resulting in works that should not be done. 'Delusion' is wrong knowledge. These arise when Tamas waxes strong. By these, one should know that the Tamas has increased very much.

14.13 Kuru-nandana, O descendant of the Kuru dynasty; when the ality of tamas vivrddhe, predominates; etani, these indications; eva, surely; jayante, come into being; extreme aprakasah, non-discrimination; and apravrttih, inactivity; its [i.e. of non-discrimination.] effects, pramadah, in-advertence; and mohah, delusion, i.e. stupidity, which is a from of non-discrimination. Whatever result is achieved even after death, that is also owing to attachment and desire; every-thing is certainly caused by the alities. By way of showing this the Lord says:

14.13 Non-illumination, inactivity, negligence and even delusion - these arise, O Arjuna, when Tamas prevails.

14.13 O descendant of the Kuru dynasty, when tamas predominates these surely [i.e. without exception.-M.S.] come into being: non-discrimination and inactivity, inadvertence and delusion.
