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.
Discriminate within yourself between the real and the unreal. Have you not read the Vedanta? Even when you sleep, keep the sword of discrimination at the head of your bed, so that covetousness cannot approach you even in dream. Practicing such strength, renunciation will gradually come, and then you will see the portals of heaven are wide open to you.
-Swami Vivekananda
