Sri Aurobindo's philosophy on teaching can be summarized as follows: 1. Sri Aurobindo believed in three main principles of teaching - that nothing can be taught, the mind should be constantly consulted in its growth, and teaching should progress from near to far. 2. He advocated for methods like teaching through the mother tongue, according to the interests and nature of each child, using practical experience, and cooperation between teachers and students. 3. Sri Aurobindo felt subjects should be taught successively to build a strong foundation, and teaching should involve training all aspects of the student through methods like observation, sense training, and appealing to their natural curiosity and faculties.
