"One mighty deed can change the course of things.” The issue in the context of Savitri’s birth in the mortal world has been defined. One shall arrive and master the course of events. Now (Savitri, pp. 20-21)

…wisdom comes, and vision grows within;

Then Nature's instrument crowns himself her king;

He feels his witnessing self and conscious power;

His soul steps back and sees the Light supreme.

A Godhead stands behind the brute machine.

This truth broke in in a triumph of fire;

A victory was won for God in man,

The deity revealed its hidden face.

The great World-Mother now in her arose:

A living choice reversed fate's cold dead turn,

Affirmed the spirit's tread on Circumstance,

Pressed back the senseless dire revolving Wheel

And stopped the mute march of Necessity.

A flaming warrior from the eternal peaks

Empowered to force the door denied and closed

Smote from Death's visage its dumb absolute

And burst the bounds of consciousness and Time.

That is the celebration of the arrival of the warrior with a “conqueror’s sword”. Savitri’s one single task is to dissolve Death. The “seeker of the Unknown and the Unborn, carrying a light from the Ineffable”, she shall concentrate on removing the last veil of Death spread over the great Mystery of this mortal creation. The epic Savitri asserts it, asserts it in the greatness of Savitri’s spirit. In its wake other things will follow. Removal of Death is the prerequisite, the necessary and sufficient condition for the truer growth of the soul of the earth in the expanding worlds of the Truth, the Right, the Vast, satyam-ŗtam-bŗhat—and that is what it has undertaken to present. Physical transformation and the new creation are the things to follow in this sequel. In that sense, Savitri’s task is specific, clear-cut, precise; it is to focus and resolve the issue the incarnate She is going to face.

This means, what Savitri was told to do that she has done, done in “What Thou Willest, What Thou Willest.” That is the mighty deed which can change the course of things, the deed which can unlock the doors of Fate. That is what Savitri has done, done in the yogic tapasya performed through her by the divine Shakti herself.

In the Vedic description Agni can be called a flaming warrior. He is the divine Will-Force working in the material creation. He has to fight the darkness that has enguldfed it and establish the superconscient will even in Matter, that there is in it the fuller expression of the divine possibilities. About Agni Sri Aurobindo writes:

The name of this flaming godhead, Agni, derives from a root whose quality of significance is a pre-eminent force or intensity whether in state, action, sensation or movement; but the qualities of this essential significance vary. It means a burning brightness, whence its use for fire; it means movement and especially a curving or serpentine movement; it means strength and force, beauty and splendour, leading and pre-eminence; it developed also certain emotional values which have perished in Sanskrit, but remain in Greek, angry passion on one side, on the other delight and love.

The Vedic deity Agni is the first of the Powers, the pristine and pre-eminent, that have issued from the vast and secret Godhead. By conscious force of the Godhead the worlds have been created and are governed from within by that hidden and inner Control; Agni is the form, the fire, the forceful heat and flaming will of this Divinity. As a flaming Force of knowledge he descends to build up the worlds and seated within them, a secret deity, initiates movement and action. This divine Conscious Force contains all the other godheads in itself as the nave of a wheel contains its spokes. All puissance of action, strength in the being, beauty of form, splendour of light and knowledge, glory and greatness are the manifestation of Agni. And when he is entirely delivered and fulfilled out of the envelope of the world's crookednesses this deity of flame and force is revealed as the solar godhead of love and harmony and light, Mitra, who leads men towards the Truth.

Such is Savitri as a flaming warrior, “armed gloriously like the sun”, her gait as an empire of superconscience and her eye a realm of vastness stretching into the mortal world. If Agni’s task is the building up of the divine body in this mortal world, then Savitri’s is to remove the obstacle that stands across the path of such a divine Event, to remove Death. Unless her work is accomplished, Agni cannot succeed.
