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.
I am the thread that runs through all these pearls, and each pearl is a religion or even a sect thereof. Such are the different pearls, and God is the thread that runs through all of them; most people, however, are entirely unconscious of it.
-Swami Vivekananda
