PURPORT

Unless Sri Krsna Caitanya Mahaprabhu discloses the fact, no one can understand who is actually a great devotee of the Lord engaged in His service. It is therefore said in Caitanya-caritamrta (Madhya 23.39), taṅra vakya, kriya, mudra vijneha na bujhaya: even the most perfect and learned scholar cannot understand a Vaisnava's activities. A Vaisnava may be engaged in governmental service or in a professional business so that externally one cannot understand his position. Internally, however, he may be a nitya-siddha Vaisnava-that is, an eternally liberated Vaisnava. Externally Mukunda dasa was a royal physician, but internally he was the most liberated paramahamsa devotee. Sri Caitanya Mahaprabhu knew this very well, but ordinary men could not understand it, for the activities and plans of a Vaisnava cannot be understood by ordinary men. However, Sri Caitanya Mahaprabhu and His representative understand everything about a devotee, even though the devotee may externally pretend to be an ordinary householder and professional businessman.
