Prabhupāda: The same patient who is suffering, for, suppose from birth, he cannot understand that there is activities after being cured of this disease. He cannot understand. He thinks activity means lying down on the bed and drinking all bitter medicine and pass stool and urine by using, what is called, that...?
Devotees: Bed pan. Bed pan.
Prabhupāda: Bed pan. He's thinking like that. He has no idea there is better activities, better sleeping, better eating. That he cannot understand. Therefore śūnyavādi. They want to make zero. "These activities are giving me so much trouble. Make it zero." Just like sometimes one cannot tolerate the pains of diseased condition. Sometimes they commit suicide—stop these activities. So the śūnyavādi, they are like that—committing suicide; stop these activities. But they do not know that there is activities. There are... After being cured of this material disease, when one is healthy... That healthy activities are the devotional activities.
