Spinoza's Pantheism in an Einstein Quote

Here is a spectacular quote from Einstein mirroring Spinoza's pantheism: "A human being is a part of the whole called by us 'the universe'; a part limited in time and space. He/she experiences themselves as something separate from the rest-a kind of optical illusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and affection for a few persons nearest to us. Our task must to be to free ourselves from the prison by widening the circle of understanding and compassion to embrace all living creatures and the whole of nature in its beauty."
