By way of metaphor, one can describe the centre of the human experience as the being in the chest. And one can distinguish between fundamentally two different modalities, two modalities that you can experience the subject as, the subject being the self or the one that’s experiencing. In Tasawwuf we refer to one modality as nafs and the other modality as ruh.
If you truly believed that there is a designing genius, then nothing that can happen to you is outside of the plan. And that you’re always in safe hands. So it is useful to understand just how dangerous how the atheists are. But its also useful to understand, how helpful they are. They objectify for you your own kufr, your own faithlessness.
