Musar su Salmi 94:11

And just as no creature can see God, so no creature has the power to see the soul. And just as God knows the future, so does man, at such time as his spirit and his body rest from engaging in the labor necessary to provide for his needs, and when the spirit of life relaxes and is free from occupying itself with the needs of the body. Then he may see the future in his dreams. And he may even see the spirits of the dead, and places that he has never seen and people whom he has never seen, and great things and visions, which he is unable to perceive when he is awake. And just as there is no creature in the world that knows the secrets of God, so can no creature among men know the secrets that are in the heart of man, but only God, as it is written, "The Lord knoweth the thoughts of man" (Ps. 94:11).
