The Master said these rappings, etc., were all material
things, and of the body. What is needed is to rise above the material to the
realms of the purely Spiritual. Table-turning and such like were material, a
natural result, and not spiritual.
But it was possible to communicate with the dead through the
condition of the character and the heart.
