In the brilliant lecture which comprises this book the author stresses on the need to make our spiritual life all-comprehensive. Spirituality should not be narrowed down to morning and evening prayer sessions alone. True spirituality encompasses the whole gamut of human life, our every movement, our every breath. The author shows us the different ways to attain such a totally spiritualized life.
The book one must read to learn natural sciences is the book of nature. The book from which to learn religion is your own mind and heart.
