kam gatim krishna gacchati
"Arjuna said: O Krishna, what is the destination of the unsuccessful transcendentalist, who in the beginning takes to the process of self-realization with faith but who later desists due to worldly-mindedness and thus does not attain perfection in mysticism?"
Arjuna raises a doubt. After adopting a new course, if we slip, will we lose the new as well as the old courses? It is like we change the queue, thinking we may reach a counter quickly. Person was earlier enjoying worldly matters. He changed this to yoga for better life. If he slipped in yoga due to any reason, he might lose the result for whuich he started yoga. Not merely that, he had already abandoned worldly matters and so those also are not there to enjoy. He might thus lose both ways. This is Arjuna's doubt. Earlier, before starting yoga, the person might have been performing some rituals to beget children or to acquire wealth. Thinking they are all inferior objctives, he abandoned all those and resorted to yoga with enthusiasm. But in the midway in yoga, with pressures of the surrounding, the person got distracted and sliped from yoga. What is the fate of this person? Arjuna asks. This sloka reflects the average person's doubt. Shraddhayopeta = with enthusiasm started [the yoga], ayati = but is unable to put in the required efforts, calita manasa = with slipped mind from, yogo = yoga. We satrted the yoga so that we will have atman darshanam and consider all equal. But in the course, suddenly we lose ourselves when some one abuses or does bad things for us. Or suddenly, we aspire to acquire more wealth or swarga. Then, we have slipped from yoga. Yogasamsiddhim = the objective of yoga, atman sakshatkaram, aprapya = not attained, kam gatim = which destination, gacchati = will he go? Will he get Moksha or will he enjoy the pleasures of this world or will he be pushed into naraka? What is going to be the destination of this person who has slipped halfway from yoga? Sri Krishna is going to reply that he would reach good destination, in the coming slokas.
