If time exists eternally and reality is contextualized from infinite possibilities, how do you know what’s real? Well, reality is simply that which you realize to be real. In other words, your reality is defined by your perception. Your perception is a filter that allows information through based on your beliefs. Beliefs are your operating system. Some are like Windows, others like Mac or Android. The information is processed differently, yet it’s always the same information. You choose how much to see.
