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.
