awakening, and supreme consciousness. The book begins with a chapter on Param Guru Swami Nigamananda Paramahamsa Dev, whose seminal book Yogi Guru motivated Swami Chetanananda Saraswati. It reveals some mystical spiritual experiences of the author during yoga sadhana before he met Sri Vishuddhananda Saraswati (Guru Baba, a disciple of Swami Nigamananda Paramahamsa Dev); his initiation by Guru Baba, sanyas after retirement, and subsequent work as a monk contributing to society as a karma yogi (one who follows the path of selfless action) to be known as Swami Chitanananda. The book has an interesting collection of selected writings, which include Swami Chetanananda Saraswati’s discourse – Who and What is God, delivered at IIT Kharagpur.
