08. Transformation of the Physical
Fragment ID: 3398
You must not try to avoid sleep at night – if you persist in doing that, the bad results may not appear immediately, but the body will get strained and there will be a breakdown which may destroy what you have gained in your sadhana.
If you want to remain conscious at night, train yourself to make your sleep conscious – not to eliminate sleep altogether, but to transform it.
