On one of his meditation CDs Master Lin says to change blockages into Butterflies whcih are realeased ionto the universe. More usually he talks of blockages changing into smnoke or air. I found myself using butterflies in the Breathing of the Universe and felt comfortable with it. I would venture that they are interchangeable but would welcome any other thoughts about this. Partly for me it's what I find easiest to visualise - it seems different every time and sometimes it takes a while to find a way of visualising things in a more effort-free way, if that communicates.
