"Clarifying the Way" means that we determine the point we should aim at throughout our lives, based on the self that is only the self and life that is only life. This is the sole great matter, and this is what "completing the sole great matter of one's life" means. True practice begins at this point.

when any action in our day-to-day life is motivated by some expectant result, or by what only appears to be a real condition or circumstance in our life, that expectant result is very likely to be dashed to pieces.

Be very clear about this: A fool sees himself as another, but a wise man sees others as himself.49 As an ancient teacher has said: Two-thirds of our days are already over, And we have not practiced clarifying who we are. We waste our days in chasing satisfaction, So that even when called, we refuse to turn around. How regrettable.50
