Shape and appearance of the spiritual body are determined by the soul. When a soul exits, the physical defects dissolve.
When a person loses a leg due to an accident, the spiritual leg still remains intact. This spiritual leg can then cause what is known as phantom pain.
When the soul exits, the spiritual body is complete again.
-My master was expecting a friend, who came over. And that friend, master Alcar said, was missing his left arm. My master collected him from the earth and put him to sleep. When the man awakened in his spiritual attunement, the Land of Twilight, Master Alcar was standing before him and asked: ‘What did you discover now? And how do you know that you died on earth and that you entered the spiritual life?’ Immediately there came: ‘I have both my arms and that cannot happen on earth after all, I experienced the most wonderful revelation of my life.’

-Mrs Brands asks: ‘When the human being loses a leg or an arm as a result of an accident and yet sometimes complains of the pain in that lost body part, what is that then? Is that not imagination?
Jozef says: ‘Madam, that is not the aura, but the spiritual leg itself. My brother Bernard felt more pain in the leg which he had lost than in the material right leg; the left, which was run over, kept reacting and he could not even sleep because of it. Therefore those limbs are still there, you have your arms and legs back again ‘behind the coffin’.

-Those who were deformed on earth become normal again; here disfigurement is unknown. The blind will see, the deaf will hear, those who lost arms or legs on earth will be restored to normality when they enter this life. The spiritual body cannot be destroyed. The human being who dwells here is beautiful forever.
