Traditionally, eka pada hastasana, like upavistha konasana and other postures that stretch the hips and pelvis, is associated with the svadisthana (splee/sacral) chakra. Working with this chakra is said to help increase feelings of freedom and creativity. It can help the yogi to feel more flexible, open and able to experience pleasure, particularly when combined with other postures that target this chakra.
