The Vajrasana

Vajrasana is a kneeling pose, and it takes its name from the Sanskrit word Vajra (वज्), which means diamond or thunderbolt. Asana (आसन), of course, means pose. This diamond pose is also called Adamintine Pose. Usually, breathing exercises like Pranayama, Kapalabhati, and Anulon Vilom are done sitting in this position, and it is said that in doing so, the body becomes as strong as a diamond.
