Raja Yoga or Mental Development by Yogi Ramacharaka

Raja Yoga or Mental Development explores the spiritual self through lessons on attention, perception and the training of the mind. Published under the name Yogi Ramacharaka, the work pairs philosophical discussion with exercises in concentration and self-observation.

Readers interested in historical yoga-inspired spiritual writing will find lessons on mental control, consciousness and subconscious influences. This is a period approach to inner development rather than a modern clinical psychology textbook or an asana practice guide.
