In addition to its physical benefits, ardha mandalasana is said to be a particularly beneficial posture on a spiritual level for integrating the solar and lunar aspects of the yogi’s being.
This posture is also related to the concept of mandalas, which are circular designs seen as being a microcosm of the universe, with the source of cosmic power, or the true integrated Self, at the center. As the limbs form part of a circle in ardha mandalasana, it is seen as symbolizing the meaning of a mandala.
Traditionally, ardha mandalasana is associated with the muladhara (root) chakra. This is because of the way it stimulates and opens the hips and pelvic area. Working with this chakra is said to help yogis to feel more secure, rooted and grounded.
