often associated with the yoga of one-pointedness, mahāmudrā śamatha contains instructions on ways to sit with proper posture, called the seven point posture of vairocana. the mahāmudrā shamatha teachings also include instructions on how to work with a mind that is beset with various impediments to focusing, such as raising the gaze when one feels dull or sleepy, and lowering it again when one feels overly excited. two types of mahāmudrā śamatha are generally taught: śamatha with support and śamatha without support.
