View, meditation, and action are three themes that define the practice of Buddhism and recur in all the teachings.
View refers to the way one perceives reality. Based on analysis and contemplation, it enables one to understand with certainty that phenomena do not have the solid reality usually attributed to them. Everything is interdependent, impermanent, and devoid of independent existence. The view particularly means seeing the nature of mind.
Meditation is the method of gradually assimilating the view by a process of familiarization, until it becomes one with one’s being.
Action is the process of connecting to the world by implementing the experience gained in the view and meditation through one’s conduct.
