Ascension to me always comes off as people trying their hardest to escape who they are to become what they perceive to be “better” a better to be something else than to be yourself kind of thing. Such as ascension to being soul wise something else. While I don’t necessarily consider the general concept “bad” but under the mentality of different is better yes.
the process? depends on the route you take and your view of what ascension is.
inside, soul transmutation, outside, possible clarity.
by working on yourself, practice, so forth.
