MIND Mind is nothing ,if you stay with present Mind is everything,if you stay with past and future The word nothing is empty mind (calm and silent) The word everything is full of confusion (if you put anything in your mind , that create more and more confusion ) If you learn more and more knowledge to understand the mind ,you never understand it . Only one way .... Experiment with yourself ,sit silently and clean your mind (yoga is one process that make your mind empty) .Try to do it in yourself(self realization is only one key to understand yourself, otherwise you are just body not anything , after self realization ,you are body with soul) . It is practical not theory...Jk How to Know mind?
