This is the Light Body, fully activated during an Attunement. Known as the merkaba by some and the 12D Shield by others. It is sacred geometry in action. Archangel Metatron is present with the Rainbow Ray of Light (the 12th Ray) and the meditator is using the merkaba for healing and consciousness transport. It creates out of this world experiences and anyone can learn to use it.
See that webbing below the person in mediation? That's the karmic matrix...and yes you really can rise above it.
