An analogy I heard today: We can face the sun (awakening) or the shadow (delusion), but some things need to grow in the shadow.
I am not sure if the analogy itself does much for me, as even the facing one way or another seems too much of a separation between the two. Awakening is maybe more an awakening to the whole field of sun, person, shadow and ground any anything else.
But the statement “something has to grow in the shadow” resonated with me. It points to the exploration process involved in both delusion and awakening – where only the flavor that is different. God is exploring itself in one case through the belief in an I and in the other case through realizing no I (allowing the belief in the idea of I, and any other ideas, to fall away).
