In part I, there where four Books, and in Part II, three Books and an epilogue. And the book was titled Savithri. True, in the early versions of Savithri, the three main characters were spelt as Savithri, Uswapathy and Suthyavan. In the unlit temple of immensity Waiting upon the marge of silence sat Mute with the expectation of her change. The hour was near of the transfiguring gods.
Poetic purity is heightened with spiritual experience.
We recognise in the last line, the first line of the present version. Mute with expectation of her change. The fourth version hardly carries any change in the above lines, though, one important difference in spelling is brought in we have now 'Savitri' instead of 'Savithri'. Indeed a Herculean labour and a divine patience. We should not, however, think that Sri Aurobindo took all these years to write the 23,837 lines and that he was wanting in poetic inspiration.
