Krishna loves to hear the glorification of his pure devotees.
A pure devotee is kept in the hands of Krishna just like a precious jewel. When you hold something precious in your hand, you are very careful, and similarly, Krishna holds the devotee and takes care of him.
Association with a pure devotee for even half a moment in this material world is the greatest treasure for human society.
One has to associate with a mahatma who has accepted Krishna as the supreme source of the entire creation. Without being a mahatma, one cannot understand Krishna's absolute position. A mahatma is rare and transcendental, and he is a pure devotee of Lord Krishna.
A pure devotee is the supreme transcendentalist and one has to receive his mercy for one's dormant Krishna Consciousness to be awakened. One has to associate with pure devotees. If one has firm faith in the words of a great soul, pure devotional service will awaken.
Pure devotees are interested in achieving the transcendental service of the Lord, which is non different from Him.
