Chi is actually a low-frequency, highly concentraded form of infrared radiation. This radiation is the energy that is also called your Aura by spiritual enthusiasts. Now as the Taoist concept of Chi crossed over into the West in recent years, a Western word was coined to describe it. Since Chi has a number of properties that seem similar to those of electrical energy, in the West it is called Bio-electricity . Researchers have witnessed certain test subjects who were able to consciously emit this form of energy from their bodies. This is your spiritual energy, it is present when you get goosebumps from positive stimuli and can be distinguished as a euphoric current flowing underneath your skin. It can also be observed as hot or cold. It is your vital force, the animating force behind life itself, and has always been associated with both breath and air. Everyone can manipulate it but not everyone is aware that there is some sort of energy current flowing when they get goosebumps. Getting goosebumps is only the tip of the iceberg when it comes to the euphoric feeling you can feel over your whole body or the many positive benefits that controlling your spiritual energy can bring you. Different terms from all over the world for it are Euphoria, Tension, Ecstasy, Qi, Chi, Prana, Vayus, Aura, Tummo, Orgone, Kriyas, Mana, Bio-electricity, Life force, Pitī, Frisson, The Secret Fire, Voluntary Piloerection, Rapture, Ruah, Ether, Nephesch, Chills, ASMR, Nen, Spiritual Energy, The Force, Spiritual Chills and many more.
