A Series of Lessons in Raja Yoga

A Series of Lessons in Raja Yoga by Yogi Ramacharaka (a pen name used by William Walker Atkinson) is a comprehensive guide to the principles and practices of Raja Yoga, which is one of the classical forms of yoga focusing on meditation, mental control, and spiritual development. The book presents yoga as a holistic system that integrates the mind, body, and spirit, offering practical lessons for personal transformation and self-realization.
Raja Yoga, often called the "royal path," emphasizes the mind's mastery over the physical body and emotions, aiming for a deep state of meditation and spiritual enlightenment. In this work, Atkinson distills these teachings in a way accessible to Western audiences in the early 20th century, while still rooted in ancient yogic philosophy.
