Know this, that the kingdom of goodness begins where man can no longer see the evil within himself, due to his refined perception. When one enters this kingdom, all good impulses such as security, comfort, and benevolence flourish and are no longer confined by the presence of evil.
The duller the eye, the further the reach of goodness. This is why the masses and children are always filled with cheerfulness, while the great thinkers are often consumed by gloom and grief.
Therefore, strive to refine your perception and allow the goodness within you to flourish. Only then will you truly enter the kingdom of goodness and find peace within yourself.
