Very useful in a practical way. Also much needed to remind us that, putting aside what we have been taught, all cultures are capable of producing what might be called the perennial philosophy, that which is common to the wisdom of all. Thanks!

I think some of it has good sense and power behind it.
It also matters on the person, for one person this might be enlightenment, for someone else a little different.

Wise words are always useful no matter who said them.

Our fixation on the source often shields us from the truth.
