Why is the Trinity personal with a Creator and God as the Buddhist Ground of Inter-being not?
The Buddhist Inter-being is within oneself.
The Trinity of God the Father, God the Son (Jesus Christ) and
the Holy Spirit is external beings.
Thich Nhat Hanh puts it more clearly and engaging: we all live
and move and have our being within a marvelous process of
Interbeing.
For me, this a much more meaningful and helpful finger by which
I can point to, and feel, the Mystery we call God, or the Mystery
we call Father (or Mother): The Divine is this energy of
Interbeing, this loving activity that requires us, and enables us,
to connect with others and with the physical world around us. It's
the energy, the Presence, we feel when we are connected with
others, when we love and are loved, when we open ourselves and when
we give of ourselves.
"God is love." Love is an interconnecting energy. Love is
inter-being. When we love we know God, we feel God, we are God.
