Why should we want to awaken?

The obvious answer is to end suffering. The next common answer is to satisfy the desire for truth. Looking deeper, I find another answer:
Because the experience of separateness from the awareness of unity is exquisite, sensational, and incredible. That is how it looks in my present moment.
The experience of separateness from the discriminating or personal mind, is just suffering. But suffering is sensational in its own way - we get addicted to it, spin stories from it, and seek attention and love to ease it, which are in round-about ways, tedious struggles to move toward unity.
It's not the direct experience of unity that is the most wondrous thing - that is what is taught, but it's not that. It is the awareness of manyness from oneness, the perception that, as the Buddha said, "the world is an image miraculously projected."
The rest is just details and metaphors:))
