On the mountains of truth you can never climb in vain: either you will
reach a point higher up today, or you will be training your powers so
that you will be able to climb higher tomorrow. —Friedrich Nietzsche
Mountains should be climbed with as little effort as possible and without desire. The reality of your own nature should determine the speed. If you become restless, speed up. If you become winded, slow down. You climb the mountain in equilibrium between restlessness and exhaustion. Then, when you're no longer thinking ahead, each footstep isn't just a means to an end, but a unique event in itself. —Robert M. Pirsig
Climb the mountains and get their good tidings, Natures peace will flow into you as sunshine flows into trees. The winds will blow their freshness into you and the storms their energy, while cares will drop off like autumn leaves. —John Muir
