Worlds Subtler and Subtler

In pranayama practice, “the human consciousness begins to be internalized and supersensuous perceptions begin to be possible. Worlds subtler and still subtler begin to be opened up in proportion to the consciousness itself getting more and more refined, till at last the individual consciousness merges into the cosmic and the individual becomes one with the infinite.” From the Kaivalyadham brochure Pranayama Practice and Teaching.
