Things appear solid but it is the nature of appearance to appear as something other than that which it actually is. At the most subtle level what you call the body is actually the interpenetration of energies which have come together and which one day will disperse. Beyond the level that can be observed physically, the subtle body is constantly vibrating within a spectrum of frequencies. It is like a temple bell resonating in the silence of emptiness. This resonance is the blissful taste of existence-being.
