Vipassana, also sometimes spelled vipasyana, uses breathing, combined with meditation and observation of the mind and body, to acquire knowledge of the true reality. Vipassana purifies the mind with the goal of eliminating all forms of attachment – both physical and emotional. The meditation focuses on anitya (impermanence), duhkha (sorrow or suffering) and anatman (the absence of a permanent self).
When perfected, vipassana leads to prajna (liberating wisdom) and, ultimately, nirvana (the ultimate state of enlightenment and freedom from suffering).
One type of yoga making use of vipassana meditation is Insight yoga. It integrates static and dynamic poses that focus on awareness of the physical sensations with the insights and mindfulness of vipassana meditation.
