Sri Aurobindo on Adi Shankara

“Ancient or pre-Buddhistic Hinduism sought Him both in the world and outside it; it took its stand on the strength and beauty and joy of the Veda, unlike modern or post-Buddhistic Hinduism which is oppressed with Buddha's sense of universal sorrow and Shankara's sense of universal illusion,-Shankara who was the better able to destroy Buddhism because he was himself half a Buddhist.”

“I find that Shankara had grasped much of Vedantic truth, but that much was dark to him. I am bound to admit what he realised; I am not bound to exclude what he failed to realise.”
