Answer
The pleasure derived from Krishna conscious practices is not something that a devotee should perform devotional service expecting to receive. Seeking personal enjoyment is not the motivation for devotional service.
Nevertheless, even when a devotee has no desire for personal pleasure and engages in devotional service solely for the satisfaction of Krishna, the nature of Krishna conscious activities is such that they are inherently filled with unlimited spiritual happiness.
In other words, whether one seeks that pleasure or not, it is naturally present in the process of devotional service. This is because devotional service is spiritual by nature, and anything connected with Krishna is full of transcendental bliss.
Therefore, activities such as chanting the holy name, hearing about Krishna, worshiping Him, serving devotees, studying scripture, and rendering various forms of devotional service all contain spiritual happiness within themselves. That happiness is not something artificially added; it is an intrinsic quality of devotional service.
However, the attitude of a devotee is very important. A devotee does not think, "I am performing devotional service so that I may enjoy spiritual pleasure." Rather, the devotee's mood is, "I am performing this service to give pleasure to Krishna."
This is the proper attitude and the pure motivation behind devotional service. When one's only desire is to please Krishna, the devotee naturally experiences spiritual happiness as a by-product of that loving service.
Thus, the devotee's focus is always on Krishna's pleasure, not on personal enjoyment. Yet because Krishna conscious activities are inherently blissful, unlimited spiritual happiness naturally accompanies sincere devotional service.
