When he heard that anyone can, through undivided devotion, not only recognise the cosmic might of the Lord but also experience that glory in himself, the Pandava Prince’s face must have reflected an anxiety to acquire this status. As an answer to this unasked question from Arjuna, Krishna explains here how one can grow towards this great fulfilment in life. The Krishna-plan, for finite man to gain the stature and strength of the Cosmic, seems to consist of five distinct schemes. This is clear from the conditions required of a seeker as given in this verse. They are: (1) whose work is all dedicated to the Lord, (2) whose goal is the Lord, (3) who is a devotee of the Lord, (4) who is free from all attachments, and (5) who is devoid of all sense of enmity towards everyone.
In these five schemes, we find the entire line of self-discipline summarised. Detachment from all activities, whether physical or mental or intellectual can take place only when one is constantly thinking of the Self. Enmity is possible only when one considers the other as separate from oneself. There cannot be enmity between my own right hand and my left hand. The awareness of the Oneness should be experienced through the vision of the same Self everywhere and then alone can the total avoidance of enmity with any creature be fully accomplished.
Total detachment is an impossibility at the mind-and-intellect level. The mind and intellect cannot live without attaching themselves to some thing or being. Therefore, the seeker, through God-dedicated activity, learns first to withdraw all his attachments from other things, and then to turn his mind with the fervour of devoted attachment to the Lord. In accomplishing this, all the schemes explained earlier are, indeed, very helpful.
Thus, when the whole scheme is re-evaluated, we can find in it a logic quite acceptable and perfectly psychological. Each subsequent item in the scheme is beautifully supported and nourished by the previous one. From the stanza, it is evident that the spiritual seeker’s great pilgrimage starts with God-dedicated activities. Soon, that God-principle Itself becomes his very goal in life. He will develop, in himself, a consummate liking for this glorious goal. Naturally, all his other finite attachments with the world-of-objects will end, and at last, he will come to contact the Self. Having become the Self, he recognises himself everywhere, in everything, and so, in him there cannot be any sense of enmity at all.
LOVE FOR ALL AND HATRED FOR NONE can be considered the Geeta ‘touch-stone’ to know the quality of realisation and intensity of experience a seeker has gained through his Sadhana.

Pandava, O son of Pandu; yah, he who; mat-karma-krt, works for Me: work for Me is mat-karma; one who does it is mat-karma-krt-. Mat-paramah, who accepts Me as the supreme Goal: A servant does work for his master, but does not accept the master as his own supreme Goal to be attained after death; his one, however, who does work for Me, accepts Me alone as the supreme Goal. Thus he is matparamah-one to whom I am the supreme Goal-. So also he who is madbhaktah, devoted to me: He adores Me alone in all ways, with his whole being and full enthusiasm. Thus he is madbhaktah-. Sanga-varjitah, who is devoid of attachment for wealth, sons, friends, wife and relatives, Sanga means fondness, love; devoid of them-. Nirvairah, who is free from enmity; sarva-bhutesu, towards all beings-berefit of the idea of enmity even towards those engaged in doing unmost harm to him-. Sah, he who is such a devotee of Mine; eti, attains; mam, Me. I alone am his supreme Goal; he does not attain any other goal. This is the advice for you, given by Me as desired by you.
