Thank you John!
BTW, do you mind that I call you John? 
I have a bit of guilty feeling regarding learning a new truth/things!
I always eager to learn a new truth however I entered the end phase of my life, & reflected about what did I do with my learning.  To my shame, I haven’t done much with what I learned.  Thus my feeling guilty  about learning now.  LOL!  You must feel proud that you taught many young&old peoples!  :-)
Oh well... May be the next incarnation?
So you recommend 'Beside Still Waters, Christians, Jews, and the Way of the Buddha'? 
Mahayana Buddhism is a distinct from main Buddhist teaching?
In Christ
