Actually, the Self is neither a what nor an it. Even though we use those terms to be able to somewhat communicate about the Self, you must understand that the Self is unmanifest pure being, which in its very nature is bliss. Please contemplate those three words: Unmanifest, Pure being, Bliss.
The bliss does not have a cause nor an object. It is simply the nature of the Self. Similarly the Self simply is, thus it is pure being. It has no reason to exist and it is immortal.

The Self is already perfect. Being unmanifest, how can there be any imperfection in it? How can there be anything to grow or develop?

So "awakening" is at best a reorientetion of the ignorant individuals perspective and goals in life to search for the Self, rather than for gratifying the narcissistic ignorant little self. Unfortunately several ignorant, though highly popular teachers, advocate "awakening" as a degree of enlightenment. It is not. It is still within the dream and the ego's games of self-
