Zazen is a form of seated meditation central to Zen Buddhism. Practitioners sit in a specific posture, often cross-legged, focusing on their breath and maintaining a calm, alert state of mind. The goal is to cultivate mindfulness and awareness, allowing thoughts to arise and pass without attachment. During Zazen, individuals may also practice shikantaza, or "just sitting," where the emphasis is on being present rather than achieving a specific outcome. This practice can lead to greater insight, emotional balance, and a deeper understanding of oneself and the nature of reality.
