08. Transformation of the Physical
Fragment ID: 3388
It is not possible to do at once what you like with the body. If the body is told to sleep only 2 or 3 hours, it may follow if the will is strong enough – but afterwards it may get exceedingly strained and even break down for want of needed rest. The yogis who minimise their sleep succeed only after a long tapasya in which they learn how to control the forces of Nature governing the body.
