“The pendulum of the mind oscillates between sense and nonsense, not between right and wrong.” – Carl Jung
A nice one illustrating how our own entire life is simply an argument for our own unique perspective, bound by our oscillations, and regardless of morals. Thus the importance of gaining perspective(s) and expanding awareness(es), that is to navigate the cosmos.
“Be melting snow. Wash yourself of yourself.” – Rumi
This one suggests that the oscillations that form the boundaries of our perspective are ego based, that we can reset these boundaries by melting them. That is if you care for expansion, or more importantly that it makes sense to you.
