BG 3.32

But those who, out of envy, disregard these teachings and do not follow them regularly are to be considered bereft of all knowledge, befooled, and ruined in their endeavors for perfection.

3.32. But those who, finding fault, do not follow this doctrine of Mine-be sure that these men to be highly deluded in all [branches of] knowledge and to be lost and brainless.

3.32 But they who ridicule My word and do not keep it, are ignorant, devoid of wisdom and blind. They seek but their own destruction.

3.31-32 Ye Me etc. Ye tvetat etc. Taking shelter in this doctrine whosoever performs any action, it does not bind him. On the other hand those, who have no faith is this knowledge, are lost totally; for, they are constantly socked in the fear of birth, death etc.

3.32 But those who do not follow this view of Mine, namely, that the self has Me for Its support, is subservient to Me and is actuated by Me only, i.e., those who do not perform all acts contemplating in this way as also those who have no faith in the meaning of the Sastras and calumniate them - know them to be extremely deluded and devoid of reasoning and knowledge and conseently completely lost. For, the function of the mind is the determination of the real nature of things, and in its absence, those mentioned above are devoid of reason, and therefore apostates in knowledge and extremely deluded in all ways. For one united with the Prakrti (body), the sense of agency results from the preponderance of the Gunas of Prakrti. But this agency really rests with the Supreme Person. Contemplating thus, Karma Yoga alone should be practised by both - those who are competent for Karma Yoga only and those who are competent for Jnana Yoga. The implied superiority of Karma Yoga has the following justifications; it is easy to perform, free from liability to lapse, and independent of anything else; it comprises the knowledge of the self also within its scope. On the other hand Jnana Yoga is difficult to practise, is not free from the liability to lapse, leaves one dependent on actions for the sustenance of the body etc. And for a distinguished perosn, this (i.e., Karma Yoga) is especially what ought to be practised. Next, till the end of this chapter, it is explained how Jnana Yoga, being difficult, is liable to lead to lapses.

3.32 Tu, but; ye, those who are the opposite of them (the former); who abhyasuyantah, decrying; etat, this instruction of Mine; na, do not; anutisthanti, follow; me, My; matam, teaching, they are deluded in various ways with respect to all knowledge. Viddhi, know; tan, them; sarva-jnana-vimudhan, who are deluded about off knowledge; acetasah, who are devoid of discrimination; nastan, to have gone to ruin. 'For what reason, again, do they not follow your teachings, perform duties that are not theirs and not follow their own duties? How is it that by remaining opposed to You, they do not fear the evil which will arise from transgressing Your ?ndments? As to that, the Lord says:

3.32 But those who calumniate it, and those who do not practise this teaching of Mine - know them to be absolutely senseless and devoid of all knowledge, and therefore lost.

3.32 But those who, decaying [Finding fault where there is none.] this, do not follow My teaching, know them-who are deluded about all knoweldge [Knowledge concerning the alified and the un-alified Brahman.] and who are devoid of discrimination-to have gone to ruin.
