How to land using horizon?
I think the GIST here is:

Look far ahead. Don't look at whatever is directly in front of you.

It's the same as driving. If one looks at the piece of concrete just meters ahead, then the barricade will "pop out in front suddenly" or the bumper of the car is "in your face out of nowhere".

Our peripheral vision will guide us to wherever we want. It is natural and in-born, biologically. You just need to know where to look.
