The science behind Raj yoga
By channeling the ego through the divine path one attains higher purpose and through that man attains perfection and liberation . Through the power of concentration one attains the highest knowledge ,the knowledge of Universe . But how can we be sure that by channelizing our ego through the divine path ,we will not lose our personalities? What is a personality ,it is the feeling of "I" which causes and forms the layers in a personality . Personality is relative in nature ,it can not become or feel eternal and fulfilled as the personality itself relies upon external factors which are subjected to constate state of flux ,as everything is changing ,forming ,breaking and again and again this process continues to be existent ,hence we are also bound to change as we too are physical bodies made up of the same matter ,which manifested the Universe . Hence ,we see that we are at basic physical level ,we are fundamentally same beings sharing same traits and likes and dislikes
