But that knowledge does not come by learning names and forms. On the contrary it comes from unlearning. Do not be surprised therefore if you read in some books of the East that Mahatmas went into the mountains and sat there for many years. I do not say that we should follow their example, but we can appreciate what they have brought from there. They went there to explore life, that aspect of life which is unseen and remains unexplored. They sat there for years in meditation. They lived on leaves and fruits, on what they could find in the forest. They contemplated. What they have thus gathered is not a knowledge learned from this world, but a greater knowledge which can be learned from within.
