Quantum physics suggests the existence of multiple universes and that mankind may be able to access these realms in the not too distant future. Usually these scenarios are played out with great advances in technology, super computers, and complex machines. Perhaps exploration in the quantum universe begins within a mind which already allows one to travel into the past and imagine the future.
Meditation and clairvoyant practices help condition the human brain into becoming a positive receptor for universal energies. By strengthening the subconscious link to the cosmos mankind might discover new ways of traversing the universe without leaving Earth. How this knowledge is attained remains a deeply philosophical idea. Each day is a step closer to knowing the truth.
