The five movements or functions of prana are called prana vayus (vayu = “wind”).
A well-rounded asana practice works all the prana vayus.
- Not the same as the general term of prana
- Governs intake, forward momentum
- Governs circulation
- Governs assimilation, absorption
- Governs growth, expression
- Upward movement
- Governs elimination
- Downward movement
WORK All Pranas
One should consider the role of all five pranas in asana practice. An integral asana practice should work all the pranas. It requires energization (prana), expansion (vyana), contraction (samana), upward movement (udana) and downward movement (apana) in the right proportion and balance. But the degree of these pranic movements will vary by condition and by dosha. – Dr. David Frawley & Sandra Summerfield Kozak
