In the 1970s an experiment showed that atomic clocks on fast-moving planes display time moving slower than atomic clocks sitting on earth. We know through Einstein’s Theory of Relativity that Time is relative to space and speed.
In Einstein’s theory, gravity can bend spacetime, and therefore time itself. The closer the clock is to the source of gravitation, the slower time passes; the farther away the clock is from gravity, the faster time will pass.
Time as we commonly understand it is a measurement tool - a way to piece the present moment into intervals and to create a separation of moments. It’s all in all an idea or a form of perception.
In the quantum realm, the modern idea of time is actually a farce. There are infinite quantum potentialities simultaneously existing on various planes and in no particular order of past, present and future. It’s more resonant to a cycle or circular pattern, as like the ouroborus, the end and the beginning are inseparable.
This is why I love working with visualization and find it to be so powerful, and also why I caution against reliving the past. Your emotions and visual set point are what draw you to your quantum possibility.
While most people live on autopilot and allow their habits and predetermined emotions to choose for them their present quantum set point, an awakened soul consciously chooses their quantum present.
Through developing powerful meditative practices, the Tantric yogi is able to transport their consciousness into any past or future perception. Astral and dream experiences can give a glimpse as to what this is like.
