Intolerance. . .

"Intolerance lies at the core of evil.

Not the intolerance that results
from any threat or danger.
But intolerance of another being who dares to exist.
Intolerance without cause. It is so deep within us,
because every human being secretly desires
the entire universe to himself.
Our only way out is to learn
compassion without cause. To care for each other
simple because that ‘other’ exists."
- Rabbi Menachem Mendle
