Road Map

You're given a map. The map has precise directions. Go this many feet
in this direction that many feet in that direction etc. The directions
are very clear down to the last detail. Everything is spelled out
exactly and precisely. There's one problem, the map doesn't indicate
where the starting point is. The map is useless.

This is how Larry described learning Kabbalah from the wrong places.
All the details are correct. They're just missing the whole point.
