“There are simple postures for Prāṇāyāma and Dhyāna,
so that we can relax in the body and not be distracted by it.
There are challenging postures,
to enable us to master our bodies and for young people who
will be engaged by the performance aspect of the posture.
There are also corrective postures.”
