The sign of true intelligence is that it has no attachment to the familiar, the comfort zone, it actively seeks to push and exceed its thought-concocted imaginary boundaries and prisons. In other words, there's no attachment to the idea of "I" hence the courage, and absence of resistance in the way of its fall hence it's giving, surrendering, and goes all the way for love for its own sake. It has nothing to save and protect of itself.
It has a sight and integrity it moves from independent of anything in the imaginary.
