Meditation forbidding mourning

I am a bag of organs on stilts walking around a solid world. The only ways I have to peer out of the dense particulation of myself are my eyes to see photons, my ears to hear airborne vibration, my nose to sense airborne chemicals, my tongue to do nearly the same, and my skin to feel the electron pressures of matter. Pay attention to the only small windows you have to know something outside of yourself. Everything happens to you through them, and you are a signal in a sea of noise.
