Samadhi in Chinese / Japanese...

三昧 is the Chinese, Japanese Kanji, and old Korean Hanja way to write Samādhi.

Samadhi is the state of intense concentration achieved through meditation.

Some will define Samādhi as putting together, composing the mind, intent contemplation, perfect absorption, or union of the meditator with the object of meditation.

In Buddhism, “三摩提” is the transliteration of the Sanskrit word Samādhi, which means equanimity, concentration, and determination.

It is one of the Buddhist practices aimed at eliminating all distractions and calming the mind.

Sometimes written in a shorter form of 三昧 (san mei).

定 is the single-character way to express the idea of Samadhi in Chinese and Japanese.

A single-character title like this is open to a lot of interpretation. So 定 can mean to set, to fix, to determine, to decide, to order, certainly, truly, settle, or compose the mind.

In the Buddhist context, this means “Perfect absorption of thought into the one object of meditation,” “The mind fixed in one direction,” “Internal state of imperturbability or tranquility,” or “Exempt from all external sensations.”

大蓮華智慧三摩地智 is the title for “The wisdom of the great lotus, samādhi-wisdom.”

This is also the penetrating wisdom of Amitābha.

正定 is one of the Noble Eightfold Paths of Buddhism. Right Concentration, along with Right Effort and Right Mindfulness, constitute the path to Concentration or Perfect Thought.

Right Concentration has to do with leaving behind sensuality, unwholesome states, as well as pleasure and pain. 正定 is a complex idea, but once you have achieved the shedding of worldly sensation, you can truly concentrate and find a higher level of awareness.

Another definition: Concentration of mind that finds its high point in the four absorptions.

This term is exclusively used by devout Buddhists. It is not a common term, and is remains an unknown concept to most Japanese and Chinese people.
