Fear, anger, misery, frustration, depression, and despair are all products of a mind that you have not taken charge of.  

Only when you are in absolute tune with existence, you know it the way it is. Otherwise you know it the way your mind interprets it.

Emotions and thoughts are not separate entities. The way you think is the way you feel.

Human beings suffer their own memory and imagination; that is they suffer that which does not exist.

The intellect is like a knife – the sharper, the better. As long as you know how to handle it.
