Seven Factors of Enlightenment 

Mindfulness (Sati) The quality of clear, lucid awareness and recollection. It is the ability to keep attention anchored in the present moment, observing phenomena as they arise without forgetting them.

Investigation of States (Dhamma-vicaya) The analytical quality of wisdom. It involves actively investigating the nature of mental and physical phenomena to understand their true characteristics (such as impermanence, suffering, and non-self).

Energy (Viriya) Mental persistence, effort, and enthusiasm. It is the drive to abandon unwholesome states and cultivate wholesome ones, preventing the mind from becoming lazy or discouraged.

Rapture (Pīti) A distinct mental factor of joy, interest, and delight. It is a spiritual happiness that refreshes and energizes the mind and body, distinct from physical pleasure.

Tranquillity (Passaddhi) The calming of disturbances in the body and mind. It is the relaxation of restlessness, tension, and agitation, leading to a state of peaceful coolness.

Concentration (Samādhi) One-pointedness of mind. It is the state where the mind becomes unified, stable, and absorbed in a single object without being distracted.

Equanimity (Upekkhā) Mental balance and neutrality. It is a state of even-mindedness that looks upon all phenomena with detachment, neither grasping at the pleasant nor pushing away the unpleasant.
