Exploring Our Subtle BodiesPart 3: The Cosmic Plane This week we dive deeper into the next three layers of our Subtle Bodies that make up the Cosmic Plane. The Cosmic Plane is the second stage of Alchemy. It is the development of the 4th, 5th, and 6th subtle bodies that we call Spirit, Atma, and Cosmic. The Cosmic Plane is where we radiate spiritually and we enter the early stages of Enlightenment.
