Losing weight

Mass and energy are different aspects of the same thing. We know that since e(nergy) = m(ass) x the speed of light squared (a constant). We also know that Conservation of Energy is one of the other fundamental laws of physics. Energy is never lost, but just changes wavelength (light to heat etc). This does NOT though apply to mass. Mass is NOT conserved.

How can this be? What does it mean in our struggle to understand meaning and existence? We can lose weight, but not energy. What happens to the weightless energy?

Certainly I think materialism isn’t the way forward. Should we focus on being – energistic. I’m told that Hindus think in terms of vibrations, auras and energy flows within their cycles of transformations. Is this where angels live – energy dissociated from mass. Any thoughts?
