Loss and Suffering as Signs of New Future

What is the energy of the future?

The energy of the future is something new which comes to replace the old.

Development occurs with an interaction of the opposites.

The main principle of the Universe and the main source of energy is time.

The difference between this cause and consequence provides the flow of energy. 

The past and the future are opposites.

The result being, that according to development law, when the future comes, the new destroys the old.

So no matter how desirable the new appears, when the new comes, we experience loss, suffering and so on.
