Cultivating our wisdom is one of our most important tasks. If we don't spend enough time alone listening to the counsel of our hearts, then we will never become wise. If we don't spend enough time in the presence of others who try to walk a path of heart, we will never become wise. If we do not cultivate, through prayer or meditation or spiritual practice, a stronger heart that can fly and endure, then we'll never become wise.
The true Word of eternity will be spoken only in solitude, where people are made desolate and estranged from themselves. This emptiness exerts a profound influence. For if something empty existed under heaven, no matter what you wish and no matter whether it be large or small, love would either carry it to heaven or have to come down and fill it with love. The purpose of emptiness is to receive, to be filled ... God needs nothing more than for us to offer a quiet heart.
