Do you believe in the existence of evil?
Only so much as what is caused where people misjudge their own interests. 'Sin' means to miss the mark.

Why do they misjudge their own interests?
Because they don't know their true selves.

Why do they not know their true selves?
Because they haven't enquired.

Why?
Because they are distracted.

Why?
Because that is the way of the world.

Why?
Because in the world
you are not
souly spirit
anymore
but also body and mind-
a tripartite being
stretched out across
the spectrums
relative
and dual.
For experience- for your own experience.
Just get it right. Aim, and hit the mark.
