How do you go beyond suffering? You have to learn to stop wanting things. First, you realize that nothing we touch, or see, or hear, or smell, or taste, will last forever. Things we perceive will only pass away after awhile. Flowers fade, parents die, the sun sets. Next, you know that the things you want will only satisfy your desire just for a period of time. As you fulfilled your wishes, you begin to want more, just to give yourself that temporal fabricated reality of happiness and the cycle continues.

In this never ending pursuit of happiness, what one goes through isn't towards happiness. Instead, it is a cruel path of suffering.
