One who identifies his self as the inert body composed of mucus, bile, and air, who assumes his wife and family are permanently his own, who thinks an earthen image or the land of his birth is worshippable, or sees a place of pilgrimage as merely the water there, but who never identifies with, feels kinship with, worships, or even visits those who are wise in spiritual truth –such a person is no better than a cow or an ass.
(Lord Sri Krsna ,Srimad-Bhagavatam 10.84.13 )
By uttering the single name of Krsna just once, one attains the same benefit as that gained by reciting Lord Visnu 's thousand names three times.
(Brahmanda Purana)
By worshiping the devotees of the Lord all one's desires will be fulfilled.
(Mundaka Upanisad (3.1.10))
When the devotees of Lord Krsna dance, their steps crush the inauspiciousness of the earth, their glances destroy the inauspiciousness of the ten directions, and their raised arms push away the inauspiciousness in the demigods' planets.
(Padma Purana and Hari-bhakti-sudhodaya (20.68))
