What does it mean? "Kali" stands for inner strength and empowerment. A "mudra" is a seal or hand gesture used in yoga or meditation practices. How do I do this? Bring the palms of your hands together and interlace your fingers. Extend the pointer fingers and cross the thumbs. When can I do it? You may have seen me demonstrate this mudra when we do our Moon Flow in Crescent Lunge and Standing Crescent.
