“While prana is not the breath, it is most readily discovered through the discipline of the respiratory function.
This, together with the heightened sensitivity that is the hallmark of yoga training, reveals the hidden secret of the breath as prana.
The word prana literally means “primary, or vital air”.
Its prefix, pra, means forward, toward, or prior. The suffix, na, means to breathe or to energize.”
