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

Right Mindfulness is about remaining focused on one's body, feelings, mind, and mental qualities. It's also about being ardent, aware, and mindful, and supposes that you've already put aside worldly desire and aversion.

Monk Bhikkhu Bodhi described this as “The mind is deliberately kept at the level of bare attention, a detached observation of what is happening within us and around us in the present moment.” When practicing right mindfulness, the mind is trained to remain in the present, open, quiet, and alert, contemplating the present event.

Another definition: Ongoing mindfulness of body, feelings, thinking, and objects of thought.

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.

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

The proper effort is not the effort to make something particular happen. It is the effort to be aware and awake in each moment, the effort to overcome laziness and defilement, and the effort to make each activity of our daily meditation. This concept is about pursuing wholesome things that promote good karma.

Another definition: Cultivation of what is karmically wholesome and avoidance of what is karmically unwholesome.

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.

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.
