Samatha meditation starts from being mindful of an object or idea, which is expanded to one's body, mind and entire surroundings, leading to a state of total concentration and tranquility (jhāna). There are many variations in the style of meditation, from sitting cross-legged or kneeling to chanting or walking. The most common method of meditation is to concentrate on one's breath (anapanasati), because this practice can lead to both samatha and vipassana'.
