Well, thanks for showing me how to use Google.
A lot of his talks avaliable were held at Wat Yansangwararam. So maybe that is where he lives.
It's not me who wants to know. I'm asking for a friend, who posted his question at a germanspeaking board.
"An important term for meditative absorption is samadhi. We often translate that as ‘concentration’, but that can suggest a certain stiffness. Perhaps ‘unification’ is a better rendition, as samadhi means ‘to bring together’. Deep samadhi isn't at all stiff. It’s a process of letting go of other things and coming to a unified experience."
