When you develop an open and carefree state of being, that is to say, non-dualistic, non-security-oriented, then the understanding of basic warmth arises. You are no longer involved with the conscious kindness of a pious and deliberate scene. You are able to give an open welcome since you have no territory of your own to preserve. The more you welcome others, the freer you become.
