Suffering exists, because of craving and aversion.
Wanted things happen and I crave for them to happen again.
Unwanted things happen and I have an aversion towards them.
Craving for a different reality makes us suffer. If you remain equanimous and aware in the present moment as it is, the suffering will cease to exist.
Seeing the impermanent nature of things; nothing worth of clinging.
Seeing the empty nature of things, everything void of a self.
My mind content, feelings, sensations just are. Nothing to worry about. They come and go. Nothing to cling to.
Everything that arises, passes away. Anicca.
Vipassana meditation is one way to realize this.
