Yeah, it may appear that from our āprogressed spiritual viewā many other views are āchildishā but the truth is that the HIgher Self wants to experience the physical reality through the lenses of all the possible views.
Additionally, we wouldnāt be as āwiseā as we are today if we and our other incarnated selves wouldnāt have gone through all those different development steps and experiences. We are literally only āthat cleverā today, because all of our past selves did all the pre-work for us. In turn, we have to give them back our understanding and love and help them through those spiritual dark ages. In the same way as our Higher Self, our version from the future, is guiding us right now with its love and understanding.
āThere is no saint without a past, no sinner without a future.ā
ā St. Augustine
