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 more we grow in love and virtue and holiness, the more we see love and virtue and holiness outside. All condemnation of others really condemns ourselves. Adjust the microcosm (which is in your power to do) and the macrocosm will adjust itself for you.
-Swami Vivekananda
