Swami Mukundananda
How do I stop being lazy when I know what I should do but don't do it?
Make body and mind your servants
Laziness is why we know what to do but don't do it. The body and mind must be subdued and made your servants. Repeatedly, with willpower, reject the lazy option.
The body and mind become whatever you mold them to be. If you give them freedom, they become the masters of your soul.
