Today I finished reading a very good book "Main Kya Hoon" by Pandit Shri Ram Sharma Acharya of Shantikuj, Haridwar.
In the book, Gurudev provides the practical methods of "Sadhana" for self attainment. He takes the readers from the knowledge of self: "What am I? my source of strength; place, time needs, means of resources and friends for me" to self realisation "So'ahamasmi-I am that " meaning My immortal soul is an inseparable and indivisible portion of the absolute spirit (Parmatman) in its ultimate state.
