Gita doesn’t teach duty, but following of divine life

The modern mind has exiled from its practical motive-power the two essential things, God or the Eternal and spirituality or the God-state, which are the master conceptions of the Gita. It lives in humanity only, and the Gita would have us live in God, though for the world in God; in its life, heart and intellect only, and the Gita would have us live in the spirit; in the mutable Being who is “all creatures”, and the
Gita would have us live also in the Immutable and the Supreme; in the changing march of Time, and the Gita would have us live in the Eternal.
Or if these higher things are now beginning to be vaguely envisaged, it is only to make them subservient to man and society; but God and spirituality exist in their own right and not as adjuncts. And in practice the lower in us must learn to exist for the higher, in order that the higher also may in us consciously exist for the lower, to draw it nearer to its own altitudes.
Therefore it is a mistake to interpret the Gita from the standpoint of the mentality of today and force it to teach us the disinterested performance of duty as the highest and all-sufficient law. A little consideration of the situation with which the Gita deals will show us that this could not be its meaning.
For the whole point of the teaching, that from which it arises, that which compels the disciple to seek the Teacher, is an inextricable clash of the various related conceptions of duty ending in the collapse of the whole useful intellectual and moral edifice erected by the human mind.
In human life some sort of a clash arises fairly often, as for instance between domestic duties and the call of the country or the cause, or between the claim of the country and the good of humanity or some larger religious or moral principle.
An inner situation may even arise, as with the Buddha, in which all duties have to be abandoned, trampled on, flung aside in order to follow the call of the Divine within.
I cannot think that the Gita would solve such an inner situation by sending Buddha back to his wife and father and the government of the Sakya State, or would direct a Ramakrishna to become a Pundit in a vernacular school and disinterestedly teach little boys their lessons, or bind down a Vivekananda to support his family and for that to follow dispassionately the law or medicine or journalism.
The Gita does not teach the disinterested performance of duties but the following of the divine life, the abandonment of all dharmas, sarvadharm¯an, to take refuge in the Supreme alone, and the divine activity of a Buddha, a Ramakrishna, a Vivekananda is perfectly in consonance with this teaching.
Nay, although the Gita prefers action to inaction, it does not rule out the renunciation of works, but accepts it as one of the ways to the Divine. If that can only be attained by renouncing works and life and all duties, then into the bonfire they must go.
