An entire self-consecration, a complete equality, an unsparing effacement of the ego, a transforming deliverance of the nature from its ignorant modes of action are the steps by which the surrender of all the being and nature to the Divine Will can be prepared and achieved, — a self-giving true, total and without reserve. The first necessity is an entire spirit of self-consecration in our works; it must become first the constant will, then the ingrained need in all the being, finally its automatic but living and conscious habit, the self-existent turn to do all action as a sacrifice to the Supreme and to the veiled Power present in us and in all beings and in all the workings of the universe. Life is the altar of this sacrifice, works are our offering; a transcendent and universal Power and Presence as yet rather felt or glimpsed than known or seen by us is the Deity to whom they are offered. This sacrifice, this self-consecration has two sides to it; there is the work itself and there is the spirit in which it is done, the spirit of worship to the Master of Works in all that we see, think and experience.
The work itself is at first determined by the best light we can command in our ignorance. It is that which we conceive as the thing that should be done. And whether it be shaped by our sense of duty, by our feeling for our fellow-creatures, by our idea of what is for the good of others or the good of the world or by the direction of one whom we accept as a human Master, wiser than ourselves and for us the representative of that Lord of all works in whom we believe but whom we do not yet know, the principle is the same. The essential of the sacrifice of works must be there and the essential is the surrender of all desire for the fruit of our works, the renunciation of all attachment to the result for which yet we labour. For so long as we work with attachment to the result, the sacrifice is offered not to the Divine, but to our ego. We may think otherwise, but we are deceiving ourselves; we are making our idea of the Divine, our sense of duty, our feeling for our fellow-creatures, our idea of what is good for the world or others, even our obedience to the Master a mask for our egoistic satisfactions and preferences and a specious shield against the demand made on us to root all desire out of our nature.
At this stage of the Yoga and even throughout the Yoga this form of desire, this figure of the ego is the enemy against whom we have to be always on our guard with an unsleeping vigilance. We need not be discouraged when we find him lurking within us and assuming all sorts of disguises, but we should be vigilant to detect him in all his masks and inexorable in expelling his influence. The illumining Word of this movement is the decisive line of the Gita, "To action thou hast a right but never under any circumstances to its fruit." The fruit belongs solely to the Lord of all works; our only business with it is to prepare success by a true and careful action and to offer it, if it comes, to the divine Master. Afterwards even as we have renounced attachment to the fruit, we must renounce attachment to the work also; at any moment we must be prepared to change one work, one course or one field of action for another or abandon all works if that is the clear command of the Master. Otherwise we do the act not for his sake but for our satisfaction and pleasure in the work, from the kinetic nature's need of action or for the fulfilment of our propensities; but these are all stations and refuges of the ego. However necessary for our ordinary motion of life, they have to be abandoned in the growth of the spiritual consciousness and replaced by divine counterparts: an Ananda, an impersonal and God-directed delight will cast out or supplant the unillumined vital satisfaction and pleasure, a joyful driving of the Divine Energy the kinetic need; the fulfilment of the propensities will no longer be an object or a necessity, there will be instead the fulfilment of the Divine Will through the natural dynamic truth in action of a free soul and a luminous nature. In the end, as the attachment to the fruit of the work and to the work itself has been excised from the heart, so also the last clinging attachment to the idea and sense of ourselves as the doer has to be relinquished; the Divine Shakti must be known and felt above and within us as the true and sole worker.
