This book is a spiritual guidebook designed for seekers in both the East and West. The book aims to provide a clear understanding of the theory and practice of spiritual life through a curated selection of representative texts.Most selections are drawn from the Upanishads and the Bhagavad-Gita, with additional sources used for sections on meditation and morality.  The book stresses that a "divine life" is rooted in moral culture, asserting that ethics must be the foundation at every stage of spiritual development.

 The book provides a rare collection of monistic meditations, making these often hard-to-find practices accessible for constant, daily use by the reader.
