The great transcendental mystery of trancendental love in union and separation from Krishna is explained for our benefit by Srila Sanatana Goswami.
To understand the spiritual emotions which appear apparently as extreme agony that are felt by Srimati Radharani and the Gopies whilst in spiritual separation from Krishna , but that’s also felt as a specific transcendental bliss , and mysteriously even more so than the bliss of union. To try to explain , Srila Sanatana Goswami draws us into the material world . He gives the example of ice burns , the feelings of extreme burns when a body is subjected to something so very cold as ice .
Thus the extraordinary and completely unfathomable movements of spiritually surcharged minds and senses and the way they behave incomprehensibly in the hearts of Krishna’s devotees and that reaches its summit in the emotions of Srimati Radharani have been mentioned , the acayas tell us only the purest of devotees can really understand something of those trancendental hights ..
