CC Madhya 24.130
śuṣka-jñāne jīvan-mukta aparādhe adho maje
bhaktye jīvan-mukta — persons liberated in this life by discharging devotional service; guṇa-ākṛṣṭa hañā — being attracted by the transcendental qualities of Kṛṣṇa; kṛṣṇa bhaje — engage in the devotional service of the Lord; śuṣka-jñāne jīvan-mukta — so-called liberated in this life by dry, speculative knowledge; aparādhe — by offenses; adho maje — fall down.
“Those who are liberated by devotional service become more and more attracted by the transcendental qualities of Kṛṣṇa. Thus they engage in His service. Those who are liberated by the speculative process eventually fall down again due to offensive activity.
