Was Einstein a Buddhist?

Albert Einstein said:

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.

This idea of freeing ourselves from our limited self-point-of-view and embracing the whole of nature is the cornerstone of Buddhism, at least as I understand it.

Buddhism teaches that if we observe the law of karma and awaken in ourselves the good heart of love and compassion for all things living, if we purify our mindstream and gradually awaken the wisdom of the nature of our mind through this compassion, then we can become a truly human being which is connected to all that is, and ultimately become enlightened.

Thank you for your insights, Albert.
