I use this term ‘self-manifestation’ hesitantly, because it has been colonised and deprived of the meaning imbued in it by C.G. Jung. It’s worth explaining the true meaning of the term:

Jung conceived of the Self as the totality of an individual across time and space, not merely the soul as represented by a particular freeze-frame in one’s life. The Self is the transcendent object which all these freeze-frames hold in common — the provenance and continuity of the soul. The child and the man have almost nothing in common except the Self, of which they each embody a different facet. The child and the man each obscure and reveal the Self progressively over time, like a flashlight searching a dark field.

Throughout a person’s life at any given time, the Self must interact with both the individual who embodies it, and the world with which that individual is confronted.
