Donald Rothberg: Guided Meditation on Developing Concentration (Samadhi) 1

(Spirit Rock Meditation Center) Full instructions are given at the beginning for cultivating concentration (samadhi), including attention to posture, a variety of possible areas of focus (with most attention given to the breath, including on the "three-part breath"), and balancing "not too tight" and "not too loose." Then we practice mostly in silence, with a brief discussion period at the end of the sitting.
