All these paths, like all other paths, start from the false position that the seeker or practitioner is a person. They start there because that's where we are when we encounter them.
As I see it, A Course in Miracles is no different, simply another divine yoga. A Course in Miracles' gimmick is relationship. Starting from the seeker's conviction that he or she is a person, A Course in Miracles introduces the concept of true relationship with another person, and then leads the seeker to accepting it. As the seeker enters and eventually embraces the process, he or she comes to recognize that he or she and the other person are in fact one being, not just in theory but in practice, like two ends of a seesaw, and that the sense of otherness, the sense of separation, is an illusion.
That point is as far as any of the world's yogas, including A Course in Miracles, can take a seeker. But the work is not yet done. Once there, we are inwardly moved to rest our search, and to sit. We still read, we still practice, we still pray, we still contemplate. But now, what's really going on is, we ripen, from the inside out.
Eventually, spontaneously, mysteriously, in its own time and in its own way, there awakens within us an awareness that the yoga itself was in fact a divine gimmick, that our own apparent self, that every apparent self, is the Self, the Divine One. Thus, as bhaktas, we see that the object of our devotion was not God as an other, but God within, which is our Self. As hatha yogis, we recognize that breath-and-breathing is itself alive, and that its life is the One Life that is our Self, God. As karma yogis, we see that our selfless work is actually divinely Selfish, Self-ful, and that the God to whom we had devoted it is in actuality our very own Self. And as students of A Course in Miracles, we see that there is no such thing as "a person", much less two persons, that our relationship was all along with our own self, now recognized as the only Self, God.
Maturing within us, this awareness becomes wisdom, meaning it is self-activating, self-sustaining, and self-validating. Continuing to mature, wisdom becomes being, our being. Everything else falls away, until we are no longer seekers, until we are no longer. Totally transparent, we are it.
So perfect, so beautiful, so natural, and so exquisitely intimate is this delivery system, little wonder mystics from Assisi to Persia and everywhere else in between sing love songs to it.
