Do you feel for others? If you do, you are growing in oneness. If you do not feel for others, you may be the most intellectual giant ever born, but you will be nothing; you are but dry intellect, and you will remain so. And if you feel, even if you cannot read any book and do not know any language, you are in the right way. The Lord is yours.
