Sri Aurobindo's Savitri - The Auroville Radio Talks: Book VII, Canto VI, Part 4

Savitri sees how all the thoughts in her outer mind are made in her body by Nature’s earth-force, and how formed universal thoughts enter her mind from outside. She rises high above her mind to stand free from Nature. Finally even the highest spiritual thoughts, which have an automatic right to enter the mind can enter no longer. Then all grows still; nothing moves any more.
