। ॥ ४३१ ॥
In plain words
In him, the whole churn of worldly existence has gone completely still. He still has his human faculties, yet underneath he is whole and undivided; he still seems to have a mind, yet no mind actually clings to him. That is the one called liberated while still alive.
Close to the Sanskrit
He in whom the working of transmigratory existence has been stilled, who though possessing faculties is [in truth] partless, who though possessing a mind is [in truth] mindless — he is regarded as liberated-while-living.
