Meditation is a practice in which an individual uses a technique to train attention and awareness and detach from reflexive, "discursive thinking," achieving a mentally clear and emotionally calm and stable state, while not judging the meditation process itself. Techniques are broadly classified into focused (or concentrative) and open monitoring methods. Focused methods involve attention to specific objects like breath or mantras, while open monitoring includes mindfulness and awareness of mental events. Meditation is practiced in numerous religious traditions.
