Start the practice of self-control with some penance; begin with fasting.

Eating constitutes the greatest obstacle to self-control; it gives rise to indolence.

To remain strong in the effect as the Self (Swaparinaam) such that, ‘This is an effect of the non-Self (parparinaam) and it is not My effect;’ that is known as penance (tapa).

The Lord used to See His own penance Himself! 

What can be referred to as true internal penance? It is when the heart is actually burning within and One peacefully remains as the Knower-Seer of that.

The penance and renunciation that one is told to do is actually under the authority of the non-Self (parsatta). So how can that happen? Penance-renunciation, it is all a resultant effect of the non-Self (parparinaam). It is neither an effect of the Self (Swaparinaam) nor is it independent (swadhin).
