"Oh, yes, I grok marks, Jubal.  At first I did try to preach free - just give it away.  I had plenty of money, I thought it was all right.  It didn't work.  We humans have to make considerable progress before we can accept a free gift, and value it.  Usually I never let them have anything free until about Sixth Circle.  By then they can accept... and accepting is much harder than giving."
