Yes, it's the same energy that powers both physical and non-physical actions - just at different "voltages" so to speak. Mental life-force energy is the power that drives and is generated by the intellect (reasoning, imagination, creative visualization). According to ancient Hawaiian understanding, mental life-force energy is many times more powerful than basic physical life-force energy (the energy produced by eating, drinking, breathing etc which drives the muscles / physical body). For example, say physical chi = 100 volts - then mental chi = 1000 volts or more.
Using a well-trained, totally focused mind and will (focusing intent or visualizing), martial artists and energetic healers etc direct the body's basic physical chi toward their specific goal. Through that mental action, they ramp the physical body's basic chi up to the level of mental life-force energy, which is many times more powerful. This is how the masters of the martial arts and Eastern healing modalities are able to accomplish their outstanding physical feats - by training the mind and the will to direct their physical chi toward the purpose at hand, thus "ramping" the physical chi up to the level of mental chi.
