Devotional service is dependent on the mercy of Krishna and His Devotees. Unless we surrender to the lotus feet of a pure devotee, it is not possible to come to the platform of pure devotional service. By his own efforts a bee cannot taste the honey within a bottle. The bottle must be opened by a superior. If the bee simply licks the outside of the bottle, thinking “Now I am tasting honey,” Then he is in illusion. Similarly, no one can enter into devotional service unless the door is opened by a devotee.
We Should know in perfect consciousness that human life is bestowed upon the conditioned soul to achieve spiritual success and the easiest possible procedure to attain this end is to chant the holy name of the Lord. – Srimad Bhagavatam, 02.01.12.
Many fanatic spiritual movements have come and gone, but without the flawless philosophy of Krishna, they cannot stand. Therefore I want especially that my books and literature should be distributed profusely. This is our substance, real philosophical information, not some weak sentiments. So try for this, to give all men this Krishna Philosophy and many real devotees will come with us back to home, back to Godhead.
Just as a bee is always interested in the honey in the flower and does not consider the thorns and colors, highly qualified persons, who are uncommon, accept only the good qualities of others, not considering their bad qualities, whereas the common man can judge what are good qualities and what are bad qualities.
Srimad Bhagavatam 4.4.12,
