Let a man strive to purify his thoughts. What a man thinketh, that is he; this is the eternal mystery. Dwelling within himself with thoughts serene, he will obtain imperishable happiness. 
Ones own thought is ones world. What a person thinks is what he becomes.
Where there is joy there is creation. Where there is no joy there is no creation: know the nature of joy.
You are what your deep driving desire is; As your deep driving desire is, so is your will; As your will is so is your deed; As your deed is so is your destiny.
