It is said that a single pure devotee of the Lord can deliver all the fallen souls of the world. Thus one who is actually in the confidence of a pure devotee like Nārada or Śukadeva Gosvāmī and thus is empowered by one’s spiritual master, as Nārada was by Brahmājī, can not only deliver himself from the clutches of māyā, or illusion, but can deliver the whole world by his pure and empowered devotional strength. The comparison to the autumnal rain that falls on muddy reservoirs of water is very appropriate. During the rainy season, all the waters of the rivers become muddy, but in the month of July-August, the autumn season, when there is a slight rainfall, the muddy waters of the rivers all over the world become at once clear. By addition of some chemical, a small reservoir of water like that of a metropolitan waterworks tank can be cleared, but by such a tiny effort it is not possible to clear up all the reservoirs of water like the rivers. A powerful pure devotee of the Lord, however, can deliver not only his personal self but also many others in his association.
In other words, the cleansing of the polluted heart by other methods (like the culture of empiric knowledge or mystic gymnastics) can simply cleanse one’s own heart, but devotional service to the Lord is so powerful that it can cleanse the hearts of the people in general, by the devotional service of the pure, empowered devotee. A true representative of the Lord like Nārada, Śukadeva Gosvāmī, Lord Caitanya, the six Gosvāmīs and later Śrīla Bhaktivinoda Ṭhākura and Śrīmad Bhaktisiddhānta Sarasvatī Ṭhākura, etc., can deliver all people by their empowered devotional service.

Pamho agtacbsp, that’s very true because BHAKTI DEVI IS VERY CONTAGIOUS , just see what a single pure devotee like HDG ACBSP DONE globally by making the whole world to chant hare krsna,SRILA PRABHUPADA was old when come to preach in the western countries but HE WAS VERY ATTRACTIVE BECAUSE OF BHAKTI DEVI BEYOND THE FACTOR TIME therefore was attractive after all KRSNA IS ALL ATTRACTIVE therefore HIS pure devotees are attractive and SUDURLABHA VERY RARE.BHAKTI DEVI MAKE ONE FREE FROM SIN FIRST in such a way that one find easy to surrender to SRI KRSNA with the relationship established because without the SAMBHANDA JNANA ESTABLISHED NOBODY CAN SURRENDER.SRI RASIKANANDA TOOK ALL HIS DISCIPLES WITH HIM AT TIME OF DEPARTURE because all of them were in raga bhakti and could not tolerate the separation from their guru .BHAKTI DEVI IS SVARAT COMPLETELY INDIPEDENT LIKE SRI KRSNA and SHE TAKE BACK HOME whoever chant hare krsna purely as already happened to bhakta valerio etc…agtacbsp ys haribol
