If man did not have his mind, the only place where he could exist would be paradise. Without intellect he has no place on the earthly world. He would always be the incorporated one who would have to sacrifice his earthly existence for the sake of the stronger ones until there would be no man left.
Without mind the human being would be therefore only a soul existence. A vibration – if one wants to call it so – which would be manifested no more materially. Just like all „extinct“ species or extinct tribes and ethnic groups.
So the mind actually prevents our entry into paradise. Our return. Because it does not want to die. And certainly not die out. That would be the beacon, which would snatch the last rest of sense from him. He, who finally has to acknowledge his own death and tries to save himself and the sense with it, to bring into the field lasting values, monuments, the progress of mankind, in order not to fall into total depression and hopelessness in complete acknowledgement of the absurdity of his material existence.
