If what is seen and experienced is portrayed in the language of logic, then it is science. If it is communicated through forms whose connections are not accessible to the conscious mind but are recognized intuitively, then it is art.
If the mind, that rules the body, ever so far forgets itself as to trample on its slave, the slave is never generous enough to forgive the injury, but will rise and smite the oppressor.
Find out for yourself what are the possesions and ideals that you do not desire. By knowing what you do not want, by elimination, you will unburden the mind, and only then will it understand the essential which is ever there.
