"Who will teach the young wisdom and discipline? "
Wisdom is not taught, systems are taught. Wisdom comes from experiencing life, or it never comes at all. And life is its own discipline.
"What produces growth and progress? "
Perhaps if we are not pushed and prodded or made to feel ashamed, we will achieve our growth — and our joy as well.
Breath and attention to breath are keys to self-emptying. Attending to the breath will carry you beyond the distractions of the mind and return you to the Greater Unity of God from which you arise and in which you dwell. Just as God breathed life into Creation, so God breathes into each one of us at this and every moment. Follow the breath back to God.
