Sri Aurobindo's Savitri - The Auroville Radio Talks: Book III, Canto I

The Great Yogi-King reached the top of all that can be known, and finds it is not enough. Now he must pursue the Unknowable, He must have the realization of the infinite, eternal, Supreme Master of Creation along with the realization of the Divine Mother. The king reaches a height where he must make a tremendous choice; “All he had been and all towards which he grew must now be left behind or else transform into a self of That which has no name….The separate self must melt or be reborn into a Truth beyond the mind’s apeal”. Then the yogi-king can realize the One by whom all live, who lives by none.
