As we walk through the world we each have a self concept. We each believe ourselves to be a specific person. And as we interact we think of others as "other" specific beings. And as we setup this network of me and you, us and them, we judge the world and we judge ourselves.
The judgments we make become the source of happiness or sadness to a large extent.
But in reality, all that we believe about ourselves and all that we believe about others is just a veil of delusion. Each of us is not deluded unto our own being, but rather each of us is in fact a delusion of god. Just like a caterpillar is deluded into his current crawling fuzzy state, he will soon become a butterfly, he just has no idea how magical he really is. In our process of metamorphosis, each us will someday find enlightenment.
Perhaps it is difficult to see ourselves as god, but I think it can be very helpful to see everyone else as god.
When we meet someone who is in pain or troubled, angry, difficult, abusive, neglectful,greedy,shallow etc.. we can understand this is only temporary. The seeds of the butterfly in these people has just yet to be watered. And perhaps when we make our mistakes, we can forgive ourselves too.
Surely we are not unhappy with plants that have yet to sprout. How can we be unhappy with ourselves in light of this view.
For me when I walk about and try to see everyone as god, it makes me smile. If it is really true, that everyone is a "Buddha-to-be" , then all the suffering and turmoil, greed, materialism, wants, needs and desires... seem utterly ridiculous. How can we take any of this too seriously. This view draws me towards love and understanding and a willingness to give far more than I need to take, and it makes me realize my needs are for the most part, pretty silly.
