Mudras are said to awaken the Kundalini energy wich is sleeping inside our body. This is the most important of all Mudras therefore it is called Maha Mudra. The Sanskrit word Maha means great hence Maha Mudra is also called Great Gesture. It is great in the sense of its effects. This Mudra combines the practice of Moola Bandha, Shambhavi and Khechari Mudras simultaneously. It also employees all three bandhas, or energetic locks in order to direct prana in the body. These three bandhas are Moola Bandha at the level of the first chakra, Muladahara, or root chakra. Second is Uddiyana Bandha, at the level of the belly or solar plexus or Manipurna chakra. Third is Jalandara Bandha or chin lock at the level of Vissudhi chakra or the throat chakra. This Mudra is not a practice for beginners.
