2. Let the Zelator observe the current of his breath. 
3. Let him investigate the following statements, and préparé a 
careful record of research. 
(a) Certain actions induce the flow of the breath through the 
right nostril (Pingala) 5 and, conversely, the flow of the breath 
through Pingala induces certain actions. 
(b) Certain other actions induce the flow of the breath through 
the left nostril (Ida), and conversely. 
(c) Yet a third class of actions induce the flow of the breath 
through both nostrils at once (Sushumna), and conversely. 
(d) The degree of mental and physical activity is interdependent 
with the distance from the nostrils at which the breath can be felt 
by the back of the hand. 
4. First practice. — Let him concentrate his mind upon the act 
of breathing, saying mentally, “The breath flows in”, “the breath 
flows out”, and record the results. [This practice may résolve 
itself into Mahasatipatthana (vide Liber XXV) or induce Samadhi. 
Whichever occurs should be followed up as the right Ingenium of 
the Zelator, or the advice of his Practicus, may détermine.] 
5. Second practice. Pranayama. — This is outlined in Liber E. 
Further, let the Zelator accomplished in those practices endeavour 
to master a cycle of 10, 20, 40 or even 16, 32, 64. But let this be 
done gradually and with due caution. And when he is steady and 
easy both in Asana and Pranayama, let him still further increase 
the period. 
Thus let him investigate these statements which follow: — 
(a) If Pranayama be properly performed, the body will first of 
ail become covered with sweat. This sweat is different in character 
from that customarily induced by exertion. If the Practitioner rub 
this sweat thoroughly into his body, he will greatly strengthen it.
