Through meditation we can attract particles of immutable matter & draw them to us in order to build a new spiritual body, the body of glory

"The law of time is implacable; nothing can hold out against it. Just as we observe that a building ages and needs repair, so is this true with regard to human beings. Our buildings (we, ourselves) must be restored, rejuvenated, and enlightened; we must reconstruct them on new foundations. You will say: 'But how can we rebuild our body?' Obviously, this does not mean rejuvenating the physical body, because its ageing cannot be prevented. But this ageing process must be compensated by the construction of the spiritual body, by means of an immutable matter that can only be found very high in the subtle regions. Through meditation and contemplation we can attract particles of this matter and draw them to us in order to build a new body, a spiritual body, the body of glory. This is what St Paul meant when he spoke of the transformation of the old Adam into Christ."
