Arjuna said: O Madhusūdana, the yoga you have described is in the nature of ‘evenness’. I am not able to see its stability and prevalence because of my mind’s restlessness.
Apparently Arjuna has grasped Krishna’s instructions quite well. Yoga, Krishna exposes, says Arjuna, is ‘equalness of mind’, to be applied to every activity and interaction, as they will always evoke sukha or duḥkha. Evenness to these is the crux of yoga.
For one used to yearning for happiness, differentiating it from unhappiness, to adopt the singular attitude of evenness will be stunningly hard. That too, in and through everything he does. It is a grave challenge, compulsion. How can all people be ready for it, much less think of succeeding in this wholesome attitude and orientation? For the desultory mind, consistency in the pursuit is too hard. It is quite heartening to hear about the practice, but to actualize it is not so. Arjuna is quite skeptical on this account.
