Srimad-Bhagavad-Gita
SECOND CHAPTER — Sanjaya said:

^46:29 The sloka may also be interpreted in the sense that those who see, hear and speak of the Self are wonderful men, because their number is so small. It is not therefore remarkable that you should mourn, because the Atman is so difficult to comprehend.

^47:30 Krishna here returns to His own point of view.

^47:31 That is to say, it is the duty of a Kshatriya to fight in the interest of his country, people and religion.

^48:32 The Shastras say that if a Kshatriya fighting for a righteous cause falls in the battle-field, he at once go to heaven.

^49:34 The present argument,--slokas 33-36, assumes that the cause in hand is already proved to be right. Hence it could only be from cowardice that Arjuna could abandon it. Even a hero may be weakened by the stirring of his deepest emotions.

^49:* Vide commentary I. 6.

^51:38 It is always the desire for one of the pairs of opposites that binds. When an act is done without attachment either for itself or its fruit, then Karma can be worked out without adding to its store, and this leads to Freedom.

^51:39 Yoga:--Karma Yoga, or that plan of conduct which secures the working out of past Karma; non-accumulation of new; and the striving for Self-realisation with the whole of the will. In this discipline, one's sole object in life is Self-realisation; hence no importance is attached to anything else. Thus all actions are performed without attachment, or care for results. So no new Karma is made: only the already accumulated is exhausted. And at the same time, the whole will is left free to devote itself to the achievement of Self-realisation alone.

In the preceding slokas, 11-25, Krishna has given the point of view of the highest knowledge, the ancient Brahmajnana. In the 25th and 27th we have a purely materialistic standpoint. Slokas 28 to 37 give the attitude of a man of the world. In the 38th we have an anticipation of the Yoga. And in what is to follow, we have Sri Krishna's own contribution to the philosophy of life.

^52:52 Waste of the unfinished attempt: A religious rite or ceremony performed for a definite object, if left uncompleted, is wasted, like a house unroofed which is neither serviceable nor enduring. In Karma Yoga, however, that is, action and worship performed without desire, this law does not apply, for every effort results in immediate purification of the heart. Production of contrary results: In worship for an object, any imperfection in the process produces positive loss instead of gain. As in cases of sickness, the non-use of the right medicine results in death. The great terror: Being caught in the wheel of birth and death.

^53:53 In Karma Yoga, the one goal is Self-realisation. The undecided (that is, about the highest), naturally devote themselves to lower ideals, no one of which can satisfy. Thus they pass from plan to plan.
