A human being is a part of a whole, called by us “universe”,
a part limited in time and space.
He experiences himself, his thoughts and feelings
as something separated from the rest…
a kind of optical delusion of his consciousness.
This delusion is a kind of prison for us,
restricting us to our personal desires
and to affection for a few persons nearest to us.
Our task must be to free ourselves
from this prison by widening our circle of compassion
to embrace all living creatures and the whole of nature in its beauty.

- Albert Einstein
