I don't know that it's ever been where it needs to be in the modern world. I think we're leaving 90% of what's possible on the table. Imagine relationships without any feeling of self-consciousness from fear of judgment, without any feeling of obligation to live up to expectations. I'm talking about family, friendships, romantic, whatever.
Imagine undefined relationships that could just be whatever they are in the moment. People feeling free to be totally open with no defenses up. Letting go of needs, and just sharing what's there as long as it lasts. And when it doesn't last, not desperately grasping to hang on.
As usual, it all begins with individual growth; having the strength, self-worth and confidence to handle what would typically be deemed rejection or disappointment, but in a fully actualized being would just roll off their back with neutrality. Very tall order, given the current cultural paradigm.
