Life is imperfect, incomplete, unsatisfactory. The truth of the existence of suffering is an undeniable reality. The unification with who or what is not wanted is suffering. Separation from who or what is wanted is suffering. Not getting what is desired is suffering.

As a result of this fact we continue to seek what is pleasant and reject what is unpleasant. Endless race, from the ultimate unattainable finish line! It seems logical. But... Aimed at the right target? - No!
Suffering is not just a product of chance, fate, the world, or life.

Notice how our attention is always turned outward. Instead, how often do we carefully observe what happens in our minds where suffering germinates?
'Ah if my husband was like this, ah if my wife was like that, ah if the work colleague, ah if the neighbor ... Always the others! But if everyone cleaned up in front of (and inside) their own home, the world would be clean.
