It’s far easier than they present.
We live in a “flat consciousness society.”
Most people never develop their prefrontal cortex analytical thinking ability which is in the Beta frequency (neural oscillation or action potential firing rate) as measured in EEG’s.(about 14 to 40 Hz.)
There are oscillation rates far beyond this that range into the megahertz and gigahertz frequencies. This is how the mystics gain their abilities. Religions teach us how to do this.
Our perception of reality is a function of the frequency of consciousness from which we view it.
When we raise our consciousness above the Beta frequency we awaken and begin to perceive directly from our consciousness (external to our physical bodies) and are not restricted to our 5 senses. This is spiritual awakening or enlightenment.
Time is not just a function of the speed of light.
Time is a function of our frequency of consciousness divided by the speed of light. Time collapses as we tune to higher frequencies. This is how the prophets see into the future.
This is why a day in Heaven is like a thousand on earth.
Everyone can grow spiritually and achieve this. We are all equal in our potential.
Einstein’s failure to understand this created his error in his theory of relativity formula.
Halucinagenic drugs help, too, I bet.
