Fundamentally speaking, ladies and gentlemen, here is the really good news...: We are intrinsically good. Without exception, and without the need for analytical studies, we can say that we automatically have Buddha within us. That is known as Buddha-nature, or bodhichitta, the heart of the Buddha.
We might ask ourselves, "What is the heart of the Buddha like? Does it think the way we do?...Is it just a pious heart that does nothing but religious things...?...The answer is NO. That heart is not necessarily pious.
The heart of the Buddha is a very open heart. That heart would like to explore the phenomenal world; it is open to relating with others. That heart contains tremendous strength and confidence in itself, which is called fearlessness. That heart is also extremely inquisitive....It is expansive and sees in all directions. And that heart contains certain basic qualities, which we could call our true basic genes-our Buddha genes. We all possess those particular Buddha-genes. Isn't it strange to say that the mind has genes? But it turns out to be true.
These Buddha-genes have two characteristics. First, they are able to see through, as well as not be afraid of, the reality of the phenomenal world. We might come up with obstacles and difficulties of all kinds, but those particular genes are not afraid to deal with them. We just shed the coverings of such possibilities as we go along. Second, these genes also contain gentleness; they are ever so loving, which goes beyond just being kind. They are extremely tender and capable of reflecting themselves, even to those who don't want to relate with them. And they are absolutely free from any kind of aggression. They are so soft and kind.
The Buddha-genes are also full of a sense of humor and delight, which is referred to as great joy. When you are able to experience that such genes exist within you, you begin to feel cheerful and smile and have a sense of humor.
