The only way to cope with life being disappointing for
long periods in a row is to develop the ability to tangibly feel how
observing the disappointment is burning the negative karma.

You want something, some recognition, some attention from someone.
Every moment you think - maybe it will come now..or maybe now..
but it doesn't come..
every moment you are disappointed..every moment you feel the opportunity to
observe that negative emotion, and let it dissolve another small chunk of your ego,
let it take you back to earlier emotions and experiences from childhood and previous lives.

Let every disappointment ground you a bit more in the peace and joy that is unconditional.
