Part of the coming of age process is advancing one's understanding of the nature of individuals, and boundaries, differentials in energy, and mastering the navigation or negotiation of those boundaries.
An especially strong tendency persists in this culture for one to look within oneself, witnessing one's play of energy, and declaring that play to be reality, seeking to systematize it and formalize it and replicate its expression. For some odd reason, it seems more comfortable for people in this culture to seek to replicate what is limited to them, instead of acknowledging that they are merely a distinct play of energy, and that there is more to life, which seems much more of a comfortable conclusion to me, as this affords the lifting of the enormous burden introduced by the belief that one's pains are all there is.
This process of mastery leads to a self mastery, as part of self mastery is learning to move in a world where there are others, and often-times moving successfully requires moving with others.
This can only be done by interfacing directly with others. As to properly grasp boundaries and act in accordance with that understanding is to feel those boundaries vividly in direct interactions.
