Srila BR Sridhar Swami brings many essential teachings to light , non more important that the explanations of why the Goswami’s of Vrndavana underwent great personal austerity in their lives , extreme renunciation were shown by Rupa and Ragganatha Goswami’s particularly . The following of the impersonal Brahman schools themselves led lives of extreme renunciation, so the Gaudia Vaisnava must match that spirit. One cannot enter into the pastimes of Vrndavana with any enjoying spirit. Only dedication and devotion on the spiritual plane can be present in the heart , the Radha Krishna nitya lila pastimes are the complete opposite of what is contrived of in the minds of materialistic persons, who strongly identify with atoms ,elements, compounds and subtle conditioning. Thus the example of cut glass or diamonds has been brought out , a fool cannot distinguish between them, and will attempt to enter a Royal gala wearing glass, surrounded by yellow painted cheep metal while fellow attendees are wearing gold and the best cut diamonds. The preaching movements can accept opulences, but strictly in the service of Krishna . Thus the best of the Vaisnavas are very strict in their practical spiritual lives and perfectly situated free from an enjoying spirit, they can enter Vrndavana and serve in the astakaliya-lila therein.
The Gaudia Vaisnava acaryas have explained everything, one should seek out strictly following and highly regulated devotees, whether preachers or bhajananandis .
