The mysterious nature of time

[zenmaster]

It's one way of using contrast to integrate emotions through metaphor.

But that's sort of like saying someone removes the cause of physical pain by integrating yelling or wincing.

One doesn't integrate emotions. An emotion is an unconscious reaction to some aspect of self that had not been integrated (acknowledged and accepted). You could call this a 'misunderstanding', an 'imbalance', a 'blockage', etc. The emotion is a response to a mind pattern (such as a complex) which has been engaged by some stimulus which brought awareness close to it. What is being integrated is how one views that which is reinforcing the distortion. When the distortion being held on to is seen as being unnecessary, the pattern is balanced and becomes part of usable consciousness. That is the form of integration.
