Just a link tip to a treasure trove of amazing literature and thought. You may have heard of Sri Aurobindo through the works of Satprem who was a disciple of him and Mother and his books like "Mind of the Cells" or "Sri Aurobindo and the Adventure of Consciousness (www.auro-ebooks.com/sri-aurobi…).
Well, I just found out that there are many of his books available as e-books to download for free. Words fail to decrible the magnitude of his work, so I am sorry, you will have to read for yourself.
