This book touches briefly on the fundamental doctrines of Hindu religion and philosophy through questions and answers, and can very well form the basis of a detailed exposition of it suited to the needs of students at different levels of understanding.
The essential thing in religion is making the heart pure; the Kingdom of Heaven is within us, but only the pure in heart can see the King. While we think of the world, it is only the world for us; but let us come to it with the feeling that the world is God, and we shall have God.
-Swami Vivekananda
