What can we gain by sailing to the moon if we are not able to cross the abyss that separates us from ourselves? This is the most important of all voyages of discovery, and without it all the rest are not only useless but disastrous.
Much of our work is invisible and intangible. You cannot measure it by human means; and sometimes a period of silent reflection will accomplish more good than if the time had been spent in outward activity. Our work is immaterial where we are and what we do; the thing that matters is who we are and what we intend. Constant preoccupation with exterior work handicaps our knowledge of ourselves and of our intentions.
