A man, who realises the potential of his mind by means of introspection and contemplation, he does not lack self-confidence. He has control over his mind and he is able to realise its full potential
Do not be conformed to this world, but be transformed by the renewal of your mind, that you may prove what is the will of God, what is good and acceptable and perfect.
Be mindful of your duty to God, and do good works; and again, be mindful of your duty, and believe; and once again: be mindful of your duty, and do right. God loves the doers of good.
Those who read books cannot understand the teachings and, what’s more, may even go astray. But those who try to observe the things going on in the mind, and always take that which is true in their own minds as their standard; never get muddled.
In the sky, there is no distinction of east and west; people create distinctions out of their own minds and then believe them to be true.
