超能力 is a word that is used in both Japanese and Chinese to refer to the ability to comprehend supernatural power.

Some may translate this as psychic ability, psychic power, ESP, or PSI.

通靈 is used to speak of something with supernatural essence, psychic power, or magical power in Chinese.

神 is the simplest way to write spirit in Chinese, Japanese Kanji, and old Korean.

This single character alone will conjure up ideas of the spiritual world. 神 can also be translated as “vital awareness” as in the fact that one must know they exist to exist (I think, therefore, I am).

Other translations include:
God, deity, mysterious, divine essence, lively, spiritual being, divinity, supernatural, soul, mind, nerves, and energy. In some extended context, it can mean genius or unusual.

Japanese romanizations vary a lot when this character is combined into other words. However, shin is the original pronunciation taken from Chinese into Japanese. You'll also see it romanized as kami, gami, jin, and a few others, depending on context.

仁神術 is Jin Shin Jyutsu or Jin Shin Jutsu.

This is a practice of calming the mind and clearing the flow of Qi energy in the body. Jin Shin Jyutsu has some commonality with the practice of Reiki.

A good translation of 仁神術 would be “Benevolent Spirit Method.”

We can break that down into all of the possible meanings:

仁 = benevolence (esp. as a virtue of Confucianism), consideration, compassion, humanity, charity, kindness, or virtue.

神 = deity, soul, spirit, mysterious, psyche, god, divinity, spiritual powers, deva, divine, spiritual, or supernatural.

術 = way, method, means, art, trick, or plan. The correct romaji for this 術 Kanji should be “jutsu.” However, in martial arts, this is often written “jitsu” but in this case, “jyutsu” became common.
