Wisdom Of gurudev sri sri ravi shankar

1) Gyan Mudra Touch the tips of the index finger and thumb and keep the other 3 fingers (index, ring, and pinky finger) stretched, relaxed and joined. Also known as the chin mudra, this is probably the most familiar mudra in mainstream society. Meditators are often seen pairing this mudra with their practice. 2)Uttarabodhi Mudra Hold the hands in front of the solar plexus. Interlock the fingers. Index fingers and thumbs of both hands should be joined together. While the index fingers point to the ceiling, point the thumbs to the floor. 3)Apan Vayu Mudra The tip of the index finger should be pressed lightly against the root of the thumb and second and the third finger should touch the inner tip of the thumb. Apan vayu mudra, also known as Mritsanjeevani mudra, is a very powerful mudra. In ancient India, it was believed to save lives in the case of heart attacks. Source -  Wisdom seekers
