Mudra is an ancient Sanskrit term meaning, "gesture." We use mudras in yoga to cultivate a greater sense of awareness to certain energetic fields within the subtle body. In other words, we can use them to help us meditate and open up our chakras.
And there are literally hundreds of mudras — each with its own unique symbolism and placement of palms and fingertips. Many of us are already accustomed to Anjali Mudra (aka "Namaste"), where the hands are positioned in a prayer in front of the heart. This mudra is used in the beginning of most yoga classes to invoke spirit and intention, or at the end to seal the practice. There's also the common Gyan Mudra — the placement of index fingertips to thumbs — used in many meditation practices.
Here are seven lesser-known mudras I've chosen to give your seven chakras a little boost. You can also incorporate the mantra and color associated with each chakra to help enhance your meditative experience.
