Weil distinguishes decreation (making a created thing pass into the uncreated) from mere destruction (making it pass into nothingness). The point is to withdraw the self we have imagined ourselves to be, so that God can exist in the space we vacate; we participate in creation by consenting to our own un-making rather than by asserting an 'I'.
Weil treats moral life as governed by two forces: 'gravity', the natural downward pull by which the soul fills voids, seeks compensation, and degrades others to raise itself, and 'grace', which alone moves against that pull. Most human behavior, including apparent virtue, can be read as the mechanical operation of gravity unless grace intervenes.
Weil argues that affliction (malheur) is not intense pain but a crushing of the whole person that stamps the soul with social degradation, physical anguish, and self-contempt, making the sufferer feel complicit in their own abasement. Because affliction attacks the capacity to love, it is uprooting of life itself, and those struck by it often cannot even cry out.
Weil holds that waiting on truth with empty, patient, non-grasping attention, rather than active effort or will, is the faculty by which the soul receives both knowledge and God. We should not try to seek directly but suspend thought, leaving it available and ready to be penetrated by the object; absolutely unmixed attention is prayer.
