See the picture on the left? The picture was taken at the place where I stayed in Pacung, Bali, during my meditation with Bali Usada.
When you stand exactly on that spot and face to the lowest point where the two hills meet, you can hear the sound of water flowing from three different sources: the small river in front of you, from the pond behind you, and the fountain on your right.
But you cannot see them. You cannot hear them either.
That magnificent spot was built by nature for me. Especially for me. And I am not sharing!
