Question: What is something nobody can truly understand until they’ve experienced it for themselves?
Answer: There is a beautiful saying, “none as wise as the experienced”.
There is nothing we can truly understands until we actually go through it. True understanding is called attainment when the direct, tangible, “tasted” emotional impressions from the actual experience give us new intellect, comprehension.
Probably one of the best examples is how children can never understand what and why their parents did to them until they themselves become children.
