"The spiritual master is always offering Krsna four kinds of delicious food [analyzed as that which is licked, chewed, drunk and sucked]. When the spiritual master sees that the devotees are satisfied by eating bhagavat-prasada, he is satisfied. I offer my respectful obeisances unto the lotus feet of such a spiritual master."
The spiritual master's duty is to engage his disciples in preparing varieties of nice food to offer the Deity. After being offered, this food is distributed as prasada to the devotees. These activities satisfy the spiritual master, although he himself does not eat or require such a variety of prasada. By seeing to the offering and distribution of prasada, he himself is encouraged in devotional service.
