In addition to its physical benefits, ardha malasana is said to be calming as it releases tension from the lower body.
Traditionally, ardha malasana, like malasana, is associated with the muladhara chakra. Working with this chakra is said to help increase feelings of security, groundedness and trust.
This asana can also be practiced as part of the Chandra Namaskara or Moon Salutation sequence. In this sequence, a flowing version is practiced where the body moves fluidly from one side to the other. This sequence is thought to be good for preparing the body and mind for sleep.
