Meditation is a practice where an individual uses a technique, such as focusing their mind on a particular object, thought or activity, to achieve a mentally clear and emotionally calm state.
Meditation may be used with the aim of reducing stress, anxiety, depression, and pain, and increasing peace, perception, self-concept, and well-being. Meditation is under research to define its possible health (psychological, neurological, and cardiovascular) and other effects.
Prayer is an invocation or act that seeks to activate a rapport with an object of worship, typically a deity, through deliberate communication. In the narrow sense, the term refers to an act of supplication or intercession directed towards a deity, or a deified ancestor. More generally, prayer can also have the purpose of thanksgiving or praise, and in comparative religion is closely associated with more abstract forms of meditation and with charms or spells.
