We meditate to learn to bypass the mind.
As we are humans, we are limited by having a body and because if this we are connected to time. Hence, we meditate to overcome our limitations.
To truly realise your question we would need to leave our physical body permanently.
According to David Hawkins' work into kinesiology and his book Power vs Force there are currently no individuals that calibrate to pure consciousness. Several calibrate to around 700 out of 1000 on a consciousness scale, but this to me would mean they are still attached to their human limitations in some manner.
Jesus and Buddha calibrated at 1000 and were the essence of pure truth. (Pity we have to work with the hand me downs and human error as their teachings have been passed down) According to the teachings of Buddhism, Buddha spent MANY lifetimes meditating to achieve enlightenment. Jesus was the Son of Christ.
Could they traverse time if they so wished? I think so. But could their human form exist across time also? I would think not. So what would be the natural inclination for someone who is expanding their consciousness, especially those that are enlightened? Meditation of course! We need to leave our physical form to truly become one with consciousness and dispense with time.
One of the questions posed in David Hawkins book (mentioned above) is "Am I my body?" The answer is no. "Do I have a body?"... Yes. We are energy beings, not the physical bodies we manifest in on Earth. Have fun with your body and your time on Earth. Use it wisely and meditate to strive for higher consciousness. When you die, hopefully you can stay connected with consciousness and become truly enlightened.
