This is the first time I heard this honourable sir's name and his sermon.Ven. Ajahn Brahm's sermons pretty much sounds and almost means the same. Simple and quite eluminative... In this sermon of his, tuning your attention to the sound of distant mountain stream takes you to that silent, spacious realms of your mind in a flash.... Any one can try it and feel it for themsalves.. Thnk you for sharing this and your explainations too.
