Behind the common idea that a Yogi can know all things and answer all questions is the actual fact that there is a plane in the mind where the memory of everything is stored and remains always in existence. All mental movements that belong to the life of the earth are memorised and registered in this plane. Those who are capable of going there and care to take the trouble, can read in it and learn anything they choose. But this region must not be mistaken for the supramental levels. And yet to reach even there you must be able to silence the movements of the material or physical mind; you must be able to leave aside all your sensations and put a stop to your ordinary mental movements, whatever they are; you must get out of the vital; you must become free from the slavery of the body. Then only you can enter into that region and see. But if you are sufficiently interested to make this effort, you can arrive there and read what is written in the earth’s memory.
