About Savitri | B1C3-04 The Growth of Divinity in Man (pp.25-26)

A Seer was born, a shining Guest of Time.
For him mind’s limiting firmament ceased above,
In the griffin forefront of the Night and Day
A gap was rent in the all-concealing vault;
The conscious ends of being went rolling back:
The landmarks of the little person fell,
The island ego joined its continent:
Overpassed was this world of rigid limiting forms:
Life’s barriers opened into the Unknown.
Abolished were conception’s covenants
And, striking off subjection’s rigorous clause,
Annulled the soul’s treaty with Nature’s nescience.
All the grey inhibitions were torn off
And broken the intellect’s hard and lustrous lid;
Truth unpartitioned found immense sky-room;
An empyrean vision saw and knew;
The bounded mind became a boundless light,
The finite self mated with infinity.
His march now soared into an eagle’s flight.
Out of apprenticeship to Ignorance
Wisdom upraised him to her master craft
And made him an archmason of the soul,
A builder of the Immortal’s secret house,
An aspirant to supernal Timelessness:
Freedom and empire called to him from on high;
Above mind’s twilight and life’s star-led night
There gleamed the dawn of a spiritual day.

It is describing the first descent of an Avatar upon the earth and the stupendous change that it made in the atmosphere.
Instead of this slow endless course of the Divinity that is buried into Matter and has slowly to wake up and to rebuild the conscious being, instead of this endless process, then a sudden descent of a Supernal Consciousness from the Supreme into a being of the manifestation, made possible a hastened growth and almost a sudden change in the evolution.
