Devotional services should be “unalloyed”, without any mixture & impurities.
Krishna wants to test your determination, how much faith you have. Sometimes there is a risk of life in devotional service. Can you take risk? You can take risk only if you have faith that Krishna will protect me.
If one renders even a small amount of sincere devotional service, Krishna becomes obliged to elevate such person and what to speak of one whose entire life and soul has been dedicated to Krishna’s service.
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.
Devotional service is not a system of negation but a system of transformation.
Devotional Service is so pure and perfect that once begun, one is forcibly dragged to the ultimate success.
