Sounds similar to Taoist Outer and Inner Dissolving.
The concept in Outer Dissolving that you’re scanning for blockages (pain, tightness, stagnation) in your physical and energetic bodies.
As you encounter something, it becomes a game of changing states and letting go: ice to water, water to gas.
Ice = blocked energy
Water = releasing tension
Gas = expelling from the body
Inner Dissolving tackles the physical, energetic, emotional, mental, psychic, karma, essence.
The real magic happens when you start getting into the infinite space “inside” you.
