the unmoving senses like planets and stars reflected in a lake, from Tsoknyi Rinpoche

All your senses are open. Your ears are not blocked, nor are your eyes closed; you have feeling in all the pores of your body, and the thoughts in your mind are not blocked either. Nothing is obstructed. You are not looking right and left, fidgeting about trying to listen to this and that. "While keeping my ears open like Tsoknyi Rinpoche told me, should I now listen carefully to every single sound that comes along?" No, that is not what's meant. You do not have to listen deliberately or intently, and yet all senses are simply wide open...

In other words, leave all the senses very open and alive, not necessarily reaching out toward objects, but simply aware. Our lineage masters all agreed that you do not have to be deliberately aware of things. Rather, just allow them to be reflected, to appear by themselves. When you look at the placid surface of a clear, quiet lake at night, the planets and stars just appear there. They present themselves, and when the surface is very serene and quiet, you can see them very clearly. It's the same way with our senses when they are left wide open.
