The Doctrine and Practice of Yoga Including the Practices and Exercises of Concentration, both Objective and Subjective, and Active and Passive Mentation, an Elucidation of Maya, Guru Worship, and the Worship of the Terrible, also the Mystery of Will-Force

In this compact guide the author lays out a systematic approach to yoga that goes beyond postures, concentrating on the art of thought‑control. Readers are invited to explore two complementary modes of concentration: the outward, objective focus that sharpens skills and worldly competence, and the inward, subjective focus that turns the mind toward the subtle realms of spirit. By contrasting these paths, the book shows how balance between practical achievement and inner awakening can be cultivated.

The lessons are presented as tightly packed verses that demand careful contemplation, each sentence packed with meaning. Practical exercises in concentration, meditation, and mindful will‑power are paired with discussions of maya, guru reverence, and the deeper mystery of will. Listeners who approach the material with patience will find tools for strengthening both body and will, laying a foundation for a steady spiritual practice.
