To this Arjuna asked, in doubt, “Svāmī! If good thought is to come at the end, must one strive for it from today itself? Can one not remember then, on that day?” The Paramātma perceived this and said, “Arjuna! By doubting why such good thought should begin from today, your intellect seems to have grown badly dull. Brother-in-law! He who has made the Manas joined in abhyāsa-yoga and has cast off all other thoughts is able to attain the supreme divine Puruṣa. Without making the Manas joined in abhyāsa-yoga, the thought of remembering the supreme Puruṣa will not come to you on that day; it cannot come. Perhaps you will ask again, ‘How so?’ Consider your own case. Because you practised the arts of astras and śastras from long ago, today, in this war, you can take them up and fight with the arts you have learnt. Otherwise, if you had not learnt these arts of astras and śastras from the beginning, could you take them up today and fight? Would it be possible? No. For kṣatriyas, occasions to wage war cannot fail to arise some day or other. Precisely because of this, even if kṣatriyas have no arts, or know none, they are taught the arts of war, and they must learn them.”
