Ah! my dear Watson, there we come into those realms of conjecture, where the most logical mind may be at fault. Sherlock Holmes speaking with Dr. Watson.
A quiet mind does not mean that there will be no thoughts or mental movements at all, but that these will be on the surface, and you will feel your true being within, separate from them, observing but not carried away
He who is alone is happy. Do good to all, like everyone, but do not love anyone. It is a bondage, and bondage brings only misery. Live alone in your mind - that is happiness. To have nobody to care for and never minding who cares for one is the way to be free.
There is nothing mind can do that cannot be better done in the mind's immobility and thought-free stillness. When mind is still, then truth gets her chance to be heard in the purity of the silence.
As soon as the mind pulls out an agenda and decides what needs to change, that's unreality. Life doesn't need to decide who's right and who's wrong. Life doesn't need to know the "right" way to go because it's going there anyway.
