This is one of the finest book on philosophy I have ever read.. read it below..
There are some other wonderful books By Yogi Ramacharka like "Light on Path", "Science of Breath".. will let you know more as I finish reading them..
In search of Who am I.. I reached to a point where I know now that this world is illusion but, WHO created this illusion and WHY created it, are still my pending questions. For me my Shirdi Sai, path of Spirituality, all sciences and Self are One. Infact one yields from other. I started with Science went to Spirituality reached my Sai who i believe will help me realize Self..
