I didn’t quite understand him to be proposing a merger of traditions in this video, but instead took him to suggest that it is important to carry out research, share understanding and texts and have healthy, mutually enriching dialogue between traditions.
It surely is very inspiring to see such humility, it was just as gladdening to see the senior Theravadin monk continuously offer HHDL gestures of reverence throughout his talk.
Thanks so much for sharing this video; it really cheered me up.
