Pradyumna: "The inactive fool is in the state of foolish ignorance, whereas the self-satisfied ātmānandī is transcendental to the material state of existence. This stage of perfection is attained as soon as one is fixed up in irrevocable devotional service. Devotional service is not inactivity, but the unalloyed activity of the soul."
Prabhupāda: Soul. This is, this is the activity of the soul. You stop the activity of the body, of the mind, then you must be engaged in the activity of the soul. Actually, the soul is active, not this body and mind. As soon as the soul is out of this body, there is no activity. So the real source of activity is coming from the soul. So how it is that after one becomes liberated, he becomes inactive?
That is the theory of the Māyāvādī. Real activity begins there. Here we are active. We have got so many impediments offered by the mind and the body; and when we actually come to the platform of soul, that is liberated position. The activity should be very nice and very polished, very advanced.
