The things that happened billions of years ago and the things that are to happen billions of years from now are happenings within the illusion.+

All the years you have passed are within the illusion. Billions of past and future years belong to the illusion. 

The things that happened billions of years ago and the things that are to happen billions of years from now are happenings within the illusion. 

The illusion is an illusion is nothing to do with the invisble  Soul, the Self. The invisble  Soul, which is present in the form of consciousness, is the ultimate truth or Brahman or God in truth.

The practical life within the practical world has nothing to do with the invisible Soul, the Self. The invisble Soul is the formless substance and the witness of the illusion. 

In the realm of the truth, the substance and the witness of the illusion are one in essence. That essence is the Soul or consciousness. Thus, consciousness is the ultimate truth or Brahman or God in truth.: ~ Santthosh Kumaar
