Once the headmaster of the Thakur Bhaktivinode Institute asked Srila Saraswati Thakur, “So many devotees have given up everything, are staying in the math, and are engaged in devotional service. Why don’t they improve to the advanced stage?” Saraswati Thakur answered, “They have internal worms. They are being eaten up by worms inside. They are taking food but are not getting nourishment because of worms. They are engaging in devotional service, but the advancement is eaten by material desires and secret bad behavior. So they become weak.
