Wisdom: Do not follow the ways of your mind

O man, no matter what you have studied or how much you have
studied, do not follow the ways of your mind with conceit in your
learning. Ask a man of wisdom who is on the path and follow
his directions. If you do not meet a man of wisdom, lay your
heart open and ask even a tree or a wall. The power of God
within your heart called conscience will caution you and guide you.
It will say, “Go,” or “Don’t go,” “Right,” or “Wrong.” If
your heart is open, your conscience will provide useful fruit which
will benefit your journey through life.
