Bhakti is the one essential thing.
To be sure, God exists in all beings.
Who, then is a devotee? He whose mind dwells on God.
But this is not possible as long as one has egotism and vanity.
The water of God's grace cannot collect
on the high mound of egotism. It runs down.
He who is usually self-sufficient becomes exceptionally vain and keenly alive to fame and praise when he is physically ill. The more he loses himself the more he has to endeavor to regain his position by means of the opinion of others.
Yet some natures are too good to be spoiled by praise, and wherever the vein of thought reaches down into the profound, there is no danger from vanity. Solemn friends will warn them of the danger of the head's being turned by the flourish of trumpets, but they can afford to smile.
For some natures, changing their opinions is just as much a requirement of cleanliness as changing their clothes: for others, however, it is merely a requirement of vanity.
