Although, in the west, we generally assume that asanas are the be-all and end-all of yoga, in reality, they make up just one of the eight limbs of the yogic practices. Saying this is not, in any way, an attempt to undermine their importance but is just a little reminder that, while they have their value, there are other aspects of yoga to bear in mind as well.
There are many reasons as to why we practice asana which we’ll look at in more detail in another post. For now though, generally, the poses are designed to strengthen and lengthen the muscles allowing us to sit in meditative positions for longer periods of time. With a regular physical practice comes good physical health and, with the body in good condition, we have more time to focus on the mind and spirit.
