Relationship between happiness and negative feelings

When negative feelings and emotions come to disturb your happiness, what do you do?
First - understand these feelings will come. They come from the past. You stored them up in your subconscious yesterday, last year or may be when you were a child. And they have to come out.
Second – don't fight or struggle with them. Just watch them, observe them, accept them, but don't identify with them, they will pass with just as easily as clouds roll across the sky.

And if you do that, eventually that emotion will subside and dissolve. In fact, it will have been healed. Negative feelings (emotions) come because you thought or did something negative in the past, stored the feelings, and here they are, disturbing your happiness now.

So why not make the future full of happiness and positivity by thinking and feeling positive.
