With a 3rd person relationship with God/Buddha Mind/Big Mind, I talk about it.
With a 2nd person relationship with God, I relate to God in my immediate experience – through prayer, meditation, visions etc.
With a 1st person relationship with God, I find God behind and in front of the eyeballs.
Each are very valuable, and each have their strenghts and adds to the richness. At the same time, if I only have a 3rd and 2nd person relationship with God, it comes and goes. When I find the 1st person relationship, and see it clearly, it does not come and go in the same way. It may go into the background or the foreground, but is always present.
