The expressions were connected to each individual's values. Men are many times wont to express such personal values, until they've grown comfortable with one another. The soul comes dyed with the color of its thoughts. We live in times of incessant change, when habits and inventions vary the acceleration of that change, and our comfort with each. Change produces stress, but also opportunity to learn more about life and ones self.
Wisdom is the search for the meaning and the accommodation of it to our aging process.
Meaning changes faster than definitions, for it flows through the passages of life. What is meaningful to a teenager, has been redefined each decade of leftover life. But motive and time must accommodate each other or there is no living each moment of possibility. Our life, exempt from public haunt, finds tongues in trees, books in the running brooks, sermons in stones, and good in everything. The soul is the lung to thought, for it breathes meaning into the oft-unused space between ears, or in time between events, or in sermons preached by strangers.
