If you consider how you develop interest–you’re stimulated by life in some way. So, if you like to read a novel and you find a really riveting storyline, the novel grabs your attention and you can’t put it down. Your attention is stimulated by something. Normally in life, we’re stimulated by events and suchlike. But here (on the retreat), we’re not stimulated in the same way. We don’t have objects of interest. We don’t have things that we’re absorbing into. So, we have to bring up energy from our own resources, not because things are exciting.
