in Buddhism, a view based on a logical statement, the 4 Noble Truths, lists of definitions for single Sanscrit words.. becomes "reasonably" ethereal. things such as Emptiness..
Buddhism, particularly Mahayana, is a comfort to intellectual westerners. the fundamental basis if Buddhism is that suffering=..disatisfaction, wanting things to be other than they are, and the resulting emotional responces,..grasping, desire, anger, aversion, jealousy..
.. are a given here in Samsara, only training the mind and living the Middle Path is the way out.. and that journey usually takes many lifetimes.. the basis is that
'Nothing" Inherently Exists. the change you described is fundamental.. understanding how that works is only realized in Meditation. all aggregates are transitory, the normal mind can only deal in aggregates.. an aggregate is like a table, it has pieces.. is the leg by its self the table.? or the top, the side..
the concept of self is the chains that bind us in Samsara/cyclical rebirth into suffering, old age, death.. then a redo plus all the bad Karma you picked up last time not knowing how it really works.
you are the self/person you were at 6 years old, or at 16, or at 18.. or 35, so the self really doesn't exist, it isn't anything "Inherent".
what Buddhism is all about is training the mind to be able to see 'Subject" and 'Object" as the same. it is something that you acquire during Meditation, without you knowing it's happening.
