Multi dimensional love
One can speculate that mother nature mirrors the whole of existence, and thus the universe is filled with similar examples of this destructive force. Shiva, the destroyer of worlds gives name to the force, but also awakens the seaker to an idea that rebirth accompanies this force, and an equally destructive force must be met with one of equal regeneration.
If the universe works this way, we get many big bangs, from one single explosion of life which created the cosmos and filled her with abundant Life force, sufficient enough to create humanity a trillion fold.
