On the Day of Atonements – which is the world to come – YQV”Q is not pronounced as ADNY – which is judgment (din), and which is ‘shoe’ (na)’al – the shutting (ne-)’ilah of the door. But it does not close the door, rather it is open to receive penitents.
And because of this: the Day of Atonements prohibits the wearing (ne)’ilah of shoes, for there is no ‘union’ on it that day, for the blessed Holy One and the Shekhinah, for sometimes She, Shekhinah, remains while the blessed Holy One withdraws, and sometimes the blessed Holy One remains, while Shekhinah withdraws.
