Bhakti is in a far higher position than mukti because a persons endeavor to get liberation from the material encagement is automatically served in devotional service. The example is given here that the fire in the stomach can digest whatever we eat. If the digestive power is sufficient, then whatever we can eat will be digested by the fire in the stomach. Similarly, a devotee does not have to try separately to attain liberation. That very service to the Supreme Personality of Godhead is the process of his liberation because to engage oneself in the service of the Lord is to liberate oneself from material entanglement. Sri Bilvamangala Thakura explained this position very nicely. He said, If I have unflinching devotion unto the lotus feet of the Supreme Lord, then mukti, or liberation, serves me as my maidservant. Mukti, the maidservant, is always ready to do whatever I ask.
