"A human being is part of a whole,

called by us the '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 us.

Our task must be to free ourselves from this prison

by widening our circles of compassion

to embrace all living creatures and the whole of nature in its beauty."

Albert Einstein
