Before attempting supta vajrsana, it is best to master vajrasana. A variation of supta vajrasana can be performed by those with lesser flexibility levels in which the head does not rest on the floor and the yogi's elbows support the recline.
The mental health benefits of supta vajrasana include helping to treat anger and other negative emotions, calming the mind and improving focus.
Supta vajrasana stimulates the svadisthana chakra, which is the second chakra and the center of creativity. A balanced svadisthana chakra helps to connect with knowledge and improves perception. As an abundant source of passion, the chakra makes the yogi passionate about everything he/she does, including their work.
