Cathexis

The emotional energy fixated upon an idea, object or person.

This emotional charge can discharge within the psyche, or across the medium of consciousness.

There is a sexual energy animating the cathexis.

It's libido gives it power which transcends the mental plane.

It is the animus/anima, the shakti/shaktipat, the kundalini energy. It is the Shekinah, the Electra a feminine-negative energy.  It's power is well-known by these different names and their diverse base of understanding or disciplines.

That is the libido or sexual energy which lights the cathexis.  The energy can transform into intense emotions, love, or hate for example, as it rises in consciousness and literally up the spine through the body's electrical centers.  If blocked or frustrated, the energy can burst forth.  Or it can be controlled and released with love, as in the manner of a great sage or guru, or saint.

The cathexis is a passion, a focused emotional energy.  It's effects are not only internal Mind/body, but can be directed outward intentionally or accidentally.  Knowing this, it is important to practice discipline in the emotions, regulating, neutralizing anger before it is released.  The arts and sciences of psychology, and mysticism have advanced literature on these topics.

The power to transcend the mental plane is that of a spiritual adept.
