Krishna consciousness is an internal thing, and those who cannot see the internal truth will make much of the external cover. We do not support that. Rather we are interested in the real spirit. All the opposing elements who are interested in externals cannot touch us. Dogs may bark, but the barking of a dog has no importance. Because they make so much of the outer thing, they have no real purification of the heart to accept the pure thing, to discriminate what is purity, or what is love of Godhead, prema, after which even Brahma and Mahadeva aspire.
(Sri Guru and His Grace) Srila Sridhara Maharaja
