। ॥ ४५० ॥
In plain words
Once the ascetic has truly known his own self as untouched and detached — like open space itself — nothing that happens afterward, no future karma, can ever cling to him, not even slightly, not ever.
Close to the Sanskrit
Having fully realized his own self as unattached and indifferent, like space, the ascetic is never touched at all, at any time, by future actions.
