Does “spirit” exist? If so, what is it? A Bodhisattva is a person of loving kindness, which I have practised all my life and still try to achieve. I did not mention Ego, which is a different, narcissicist concept of "the Self". Buddhists can believe in a sub conscious state, to be achieved in deep meditation. But, we are still human beings with free will and I can and will call myself a Bodhisattva.
