Turning your energy perception around 180degrees so as to see in the void.

Ancestors are real, just like causality is real. Hypothetically we could start with any effect and follow it back to a First Cause. It's not possible in practice because everything has a million causes, but in theory contemplation goes backward and causality goes forwards.

But also gravity is very real and that doesn't stop us from flying planes or putting robots on Mars.
