There are only two energies at the core level which propel existence forward on its path. We humans perceive these as: hunger and need to reproduce. On planet Earth all other life forms, both immoveable and moveable, are also driven by these two energies. At the cosmic level, galaxies do the same, devour each other as food resulting in the birth of new galaxies. Further, all other energies invoked by humans are, indeed, subsets of these two core energies only. Life goes on, cycling through, at the human level or at the cosmic level.
