Souls

 Tanchuma (Pekudei 03) Why is it written: Who doeth great things past finding; yea, marvelous things without number? You should know that every soul, from Adam to the end of the world, was formed during the six days of creation, and that all of them were present in the Garden of Eden and at the time of the giving of the Torah, as it is said: With him that standeth here with us this day, and also with him that is not here with us this day 

Pirkei deRabbi Eliezer (34) The soul is like its Creator. Just as G-d sees and is not visible, so the soul sees and is not visible. Just as G-d has no sleep in His presence, so the soul does not sleep. Just as G-d bears His world, so the soul bears all the body. All souls are His, as it is said, "Behold, all souls are mine".
