From Genuine Mediumship OR The Invisible Powers by Swami Bhakta Vishita (Hindoo Master)

The Higher Vibrations

The vibrations of magnetism and electricity are imperceptible to our sight, though they may be registered by the appropriate apparatus; and if we had the proper sense of apparatus to perceive them, these rays of vibratory force would open up a whole new world to us. Likewise, if we could increase our power of hearing-perception, we would seem to be living in a new world of sights and sounds now closed to us. Reasoning along the same lines of thought, many great thinkers have held that there is no reason for doubting the possible existence of other world-planes of being, just as real and as actual as the one upon which we live, and move, and have our being, but which is forever invisible to the ordinary human sight and senses; the apparent nothingness of such worlds arising solely from the great difference in the rates of vibrations between the two planes of being.
