This book is a compilation of internationally acclaimed series of talks given by Pravrajika Divyanandaprana, a monastic member of Sri Sarada Math, at IIT Delhi, in 2018. Happiness is a purely subjective experience. However, the profundity of the subject is found lacking in modern discourse. The book succinctly captures stunning insights into the source, methods and techniques, levels and types of happiness. This book, in a probably first time ever, brings together the science and technology of higher consciousness, presenting the whole scheme of proceeding up the ladder of happiness in a very clear, lucid and logical format. Illumined with stories and examples to help the reader find contextual relevance, ‘Science of Happiness’ according to Yoga-Vedanta, is an absolute treat, rich with its commingling of perspectives from modern consciousness studies, fields of neuroscience, psychology and philosophy on one hand, and ancient scriptural revelations from the Yoga Sutras, Upanishads, Brahma Sutras, Bhagavad-Gita on the other. A speaker at various national and international forums, Pravrajika Divyanandaprana has been widely acclaimed for her talks on Self-knowledge, mind-management, subjective-objective sciences, etc. Her easy-to-understand narrative has enthralled audiences the world over, including the USA, Canada, South Africa, UK, Ireland and UAE.
