[6.225.3] You think that the reappearance of an already departed soul would mainly strengthen the believe in the immortality of the soul and the believe in God, and I say to you that in this regard you are stuck in a completely, fundamentally wrong opinion! Firstly a departed soul in the beyond has exceedingly more than enough to do for itself and for its neighbours and does not really has the time to appear to the people in the flesh several times with a body created from the air and the earth and to teach them how things are and look like in the beyond, and secondly can every perfect spirit in anyway influence the people without limiting their free will in the best possible manner, and such invisible influence is for man much more salutary than the visibility and audibility of a departed spirit. For if a good and already quite enlightened spirit places good and honourable thoughts and feelings in your heart, they are already as good as if you have created them in you yourself; they unify with your life and motivate you to become active.

[6.225.4] If however a spirit, as for example Moses, would appear to you and say to you: 'This and that you have to do if you want to attain life; if you are not going to do this you will fall into the judgment of the almighty God and there hardly will be any fully happy rise from the death of judgement!', you will tremble after such an admonition and will for the rest of your life not dare to do anything else than what the spirit of Moses has advised you to do.
