must be gained, equilibrium, so that the self, joined to the Self, shall not be affected by pleasure or pain, desire or aversion, or any of the "pairs of opposites" between which untrained selves swing backwards and forwards. Moderation is therefore the keynote of the Gita, and the harmonising of all the constituents of man, till they vibrate in perfect attunement with the One, the Supreme Self. This is the aim the disciple is to set before him. He must learn not to be attracted by the attractive, nor repelled by the repellent, but must see both as manifestations of the one Lord, so that they may be lessons for his guidance, not fetters for his bondage. In the midst of turmoil he must rest in the Lord of Peace, discharging every duty to the fullest, not because he seeks the results of his actions, but because it is his duty to perform them. His heart is an altar, love to his Lord the flame burning upon it; all his acts, physical and mental, are sacrifices offered on the altar; and once offered, he has with them no further concern.
As though to make the lesson more impressive, it was given on a field of battle. Arjuna, the warrior-prince, was to vindicate his brother's title, to destroy a usurper who was oppressing the land; it was his duty as prince, as warrior, to fight for the deliverance of his nation and to restore order and peace. To make the contest more bitter, loved comrades and friends stood on both sides, wringing his heart with personal anguish, and making a conflict of duties as well as physical strife. Could he slay those to whom he owed love and duty, and trample on ties of kindred?
