Emotion energy - Emotion is mental energy. If it is not expressed it flows into the body. Painful emotions (fear, anger) residing in the body can cause a neurosis if not physical problems.

Chemical energy - Eating food that lacks essential vitamins can cause depression and even schizophrenia. Pharmaceutical drugs, as well, can have mental side-effects.

Spiritual energy - Spiritual experiences - such as a kundalini awakening - happen at the level of spiritual energy. They will be viewed as mental problems.
