I figured I'd mention this source as Charles mentions anti-gravity. It's achieved through a very highly focused mind interacting with physical matter! It's a different approach to an anti-gravity device, but I resonate with the theosophy teachings and want to share what I find incase it helps. I've read similar things from past life regression books on the pyramids that they relied on the human consciousness interacting with the stones, essentially moving parts of the atom to a higher etheric state thus making the object significantly lighter and easier to move, and afterwards the object snaps back to their denser state. It's more of a forgotten ability. The etheric state is a higher vibrational state so it easily passes through solid matter. Hence why we require our consciousness as the tool to interact with it and move matter to and from it, as physical objects are too dense to affect it. Charles highlights this in the book, and the importance of a highly focused mind to hold the shape. An AI summary is copied below as it summarises the book section quite well: According to the author, true anti-gravity (or levitation) is achieved through a specific, scientific method used by Eastern Yogis and advanced occultists to consciously neutralize or completely reverse the attraction of gravity. Instead of relying on external spirits, the practitioner uses their deep mastery over "Nature's finer forces" to deliberately counteract the earth's gravitational pull. The author claims this exact method of consciously manipulating gravity is the lost secret behind how ancient civilizations easily lifted the massive blocks of stone for the Egyptian Pyramids and Stonehenge, and how the airships of ancient India and Atlantis were made light enough to fly Charles also mentions by applying extremely rapid vibrations, a practitioner can overcome the molecular cohesion of a physical object, temporarily reducing it from a solid into an "etheric condition". Once the object is reduced to this finer, subtler state, it can be moved rapidly by astral currents and passed with perfect ease through any solid substance, such as the wall of a house or the side of a locked box. To successfully move an object this way without ruining it, the practitioner must prevent it from solidifying into a shapeless lump of material upon arrival. The operator must use intense concentration and willpower to hold the object's invisible "elemental essence" in its exact original shape throughout the entire transfer
