If you want to dig for diamonds, you don't do it in a rock pile.
You have to go to where the diamonds actually are.
The same goes for whatever you are searching for, whether it is information or spiritual wisdom.
If you want to find true spiritual wisdom, go to the ROOT, not the branches.
I prefer to go straight to the Power Source, not to use old, questionable extension cords. Primary sources are always more reliable than secondary sources.
Just remember, if someone's teapot is empty, they can't share quality tea with you.
Reflect on these things and you will understand.
