"A pure devotee's position is that he has no enemy because he is not envious. A pure devotee is always open to everyone, and he does not discriminate that this person can be allowed to chant Hare Krishna and that person should not be allowed. On the material platform, which is a platform of dualism, there are differences between high and low, man and woman, and this or that, but on the spiritual platform there are no such distinctions. The pure devotee, seeing everything with an equal mind, is therefore nonenvious. Because he is nonenvious, he is worshipable. Indeed, it may be said that a person is worshipable simply if he is nonenvious, for it is only possible to be nonenvious on the spiritual platform This is also the verdict of the Bhagavad-gita (5.18-19):
brahmane gavi hastini
suni caiva svapake ca
ihaiva tair jitah sargo
yesam samye sthitam manah
nirdosam hi samam brahma
tasmad brahmani te sthitah
"The humble sage, by virtue of true knowledge, sees with equal vision a learned and gentle brahmana, a cow, an elephant, a dog and a dog-eater. Those whose minds are established in sameness and equanimity have already conquered the conditions of birth and death. They are flawless like Brahman, and thus they are already situated in Brahman.
"Such a position can be obtained by one who has acquired the mercy of Lord Caitanya. Upon obtaining His mercy, a person can deliver suffering humanity from material contamination."
