"
All your emotions are nothing but biochemical storms in your brain ... You can feel ecstasy right now, or you can feel pain or depression ... It's all up to you." - says Anthony Robbins in his book called
Awaken the Giant Within.
The way you interpret past events will eventually become your reality. The events do not exist.
Your memories are based on your reality. The inner dialogues and images inside your mind dictate the way you feel.
"... visualisation is based on the power of images that we deliberately conjure up in our minds' eye. ... biofeedback training ... has shown how affected we are ... by fleeting thoughts and mental images. It is as if our minds can make no difference between what is actually happening 'out there' ... and what is happening inside our heads. ...
Take, for example, films. Really, these are just moving images on a screen. They have no substance in reality. Yet they have the power to make us feel romantic, scared, sexually aroused and so forth ... We tend to become like ... the pictures that we carry in our minds. It is thus very important for our well-being that we dwell only on positive images." says Louis Proto in his book called Be Your Own Best Friend.
A wise man is the master of his mind whereas a fool is its slave.
