Intellect is like limbs without the power of locomotion. It is only when feeling enters and gives them motion that they move and work on others. That is so all over the world, and it is a thing which you must always remember. It is one of the most practical things in Vedantic morality, for it is the teaching of the Vedanta that you are all prophets, and all must be prophets. The book is not the proof of your conduct, but you are the proof of the book.
