On the sea lanes, the weather, even without launching companion boats, you adapt to the state of the time, sometimes taking advantage of crosswinds, sometimes even getting favourable winds, knowing that even if the wind changes you can still reach port by oar, you take command of the ship and cross the ford.
With that attitude, in passing through the human world you should also have a sense of crossing the ford in an emergency.
In martial arts, in the midst of battle, it is also essential to "cross the ford." Sensing the state of opponents, aware of your own mastery, you cross the ford by means of the appropriate principle, just as a skilled Captain goes over a sea-lane.
Having crossed over the ford, furthermore, there is peace of mind.
To "cross the ford," put the adversary in a weak position and get the jump yourself; then you will generally quickly prevail. Whether in large scale military science or individual martial arts, the sense of crossing a ford is essential. It should be savoured thoroughly.
