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.
Who will bring light to the poor? Who will travel from door to door bringing education to them? Let these people be your God -- think of them, work for them, pray for them incessantly. The Lord will show you the way.
-Swami Vivekananda
