You can't cross the river from far away. Neither can someone standing by the river help you across unless you meet them by the river.
No one can help you come from far away to the other side of something (understanding), unless you move and travel in the necessary direction. When you are close enough to the river of understanding to touch it but can't seem to figure out exactly how to get across or where the best place to cross is, then, you can be helped.
In the same manner, no one can get another person across from one side of understanding to the other, unless the other person is right there, ready and willing to cross.
So meet me at the river of understanding and be prepared to paddle your own boat because each boat only holds one person at a time.
You cannot cross a river of understanding using the power of someone else's understandings.
Why not?
Because what it took for each of you to get to the river was a different journey; thus so also will it be to get across.
