An outline of how polarities may be perceived through dualistic, transdual and nondual views…
First, the poles of the polarity are seen as absolutely different and separate from each other. One has little or nothing to do with the other. One is in here, another is out there. One is bad and should be annihilated, the other is good and should be sought. This is the mostly blindly dualistic view, and occurs if we are exclusively identified with our human self.
A slightly more sophisticated view is that the poles of the polarity are dependent on each other. We wouldn’t experience joy if there wasn’t grief, or wouldn’t know to call something light if we didn’t know darkness, and so on. This is a more conventional view and very early transdual.
Going a little further, we see that all polarities are aspects and expressions of one single process. The universe is a seamless process, and expresses itself in polarities. It is inherent in existence that we cannot have one without the other. It is the way the whole – beyond and including all polarities – expresses itself. This is more deeply transdual.
Eventually, as we awaken as Big Mind – as what is with no “I” anywhere – there is again a different realization of polarities. It includes the previous one, but now we also realize that all phenomena – expressing themselves in polarities – are Spirit, God, Buddha Mind. They are emptiness dancing. This is the One Taste experience of polarities.
