It occurred to me today that the perfect expression of the buddha nature, the perfect expression of a being at one with the dao, whatever you want to call it - is the baby on the day she is born. From there on it's spirals of increasing complexity. Many of the seekers I meet seem to think that they need to acquire something, some sort of wisdom, when instead they need to divest themselves of the intellectual trappings (good word, that) of the culture. They need to simply return to what they knew on the day they were born. Naturally, you can't go through life as a newborn baby, but if you can divest yourself at will, as needed, and remember that the tools and baggage we need to traverse our lives are fictions, then you have enlightenment and the ability to live in the world.
