Extreme affliction, which means physical pain, distress of soul and social degradation, all at the same time, constitutes the nail. The point is applied at the very centre of the soul. The head of the nail is all the necessity which spreads throughout the totality of space and time.
Affliction is a marvel of divine technique. It is a simple and ingenious device which introduces into the soul of a finite creature the immensity of force, blind, brutal and cold. The infinite distance which separates God from the creature is entirely concentrated into one point to pierce the soul in its centre.
The man to whom such a thing happens has no part in the operation. He struggles like a butterfly which is pinned alive into an album. But through all the horror he can continue to want to love. There is nothing impossible in that, no obstacle, one might almost say no difficulty. For the greatest suffering, so long as it does not cause fainting, does not touch the part of the soul which consents to a right direction.

He whose soul remains ever turned in the direction of God while the nail pierces it, finds himself nailed on to the very centre of the universe. It is the true centre, it is not in the middle, it is beyond space and time, it is God. In a dimension which does not belong to space, which is not time, which is indeed quite a different dimension, this nail has pierced a hole through all creation, through the thickness of the screen which separates the soul from God.
In this marvellous dimension, the soul, without leaving the place and the instant where the body to which it is united is situated, can cross the totality of space and time and come into the very presence of God.
It is at the intersection of creation and its Creator.
– Simone Weil, ‘The Love of God and Affliction’ (tr. Craufurd)
