Gīta Bhāshya 3.36

The question stems from the statement - "One should not come under their sway" (3.34).

बहवः कर्मकारणाः सन्ति। क्रोधादयः कामश्च। तत्रकः बलवान् इति पृच्छति - अथेति॥

bahavaḥ karmakāraṇāḥ santi। krōdhādayaḥ kāmaśca। tatrakaḥ balavān iti pr̥cchati - athēti॥

[bahavaḥ = many; karmakāraṇāḥ = actions and causes; santi = exist;। krōdhādayaḥ = the anger and others; kāmaśca = and desire as well;। tatrakaḥ = among them, which has; balavān = more strength; iti pr̥cchati = thus asks; athēti = 'atha' verse;॥]

Many actions and causes exist such as the anger, desire, etc. Among them, which has more strength? So asks in 'atha' verse.

अथेत्यर्थान्तरम्। "तयोर्न वशमागच्छेत्" इति प्रश्नप्रापकम् ॥३६॥

athētyarthāntaram। "tayōrna vaśamāgacchēt" iti praśnaprāpakam ॥36॥

[athētyarthāntaram = the word 'atha' indicates a change of context;। "tayōrna vaśamāgacchēt" = "one should never come under their sway" (3.34) iti praśnaprāpakam = from it originates the question;॥36॥]

The word 'atha' shows a change of context. The question stems from the statement - "One should not come under these twos sway" (3.34).
