The cornerstone on which all things are based is man's concept of himself.
Do not waste one moment in regret, for to think feelingly of the mistakes of the past is to re-infect yourself.
The great secret is a controlled imagination and a well-sustained attention, firmly and repeatedly focused on the object to be accomplished.
Where knowledge ends... feeling and imagination begin.
The journey of life is a mental one, which is taking place in the sea of illusion.
If you judge after appearances, you will continue to be enslaved by the evidence of your senses.
