A devotee should not be proud of his acquisitions. The symptoms of a devotee are meekness and humility. Although spiritually very advanced, he will always remain meek and humble, as Krishna Das Kaviraja Gosvami and all the other Vaisnavas have taught us by personal example. Caitanya Mahaprabhu taught that one should be humbler than the grass on the street and more tolerant than the tree. One should not be proud or falsely puffed up. In this way one will surely advance in spiritual life.
A.C. Bhaktivedanta Swami Prabhupada
A devotee should always try to hear about spiritual matters and should always utilize his time in chanting the holy name of the Lord. His behavior should always be straightforward and simple, and although he is not envious but friendly to everyone, he should avoid the company of persons who are not spiritually advanced.

The only condition for successfully executing spiritual activities is that they must be conducted under the guidance of a pure devotee who is completely free from all mundane desires.

By pleasing the devotee Bhagavata one can receive the benefit of the book Bhagavata. Human reasoning fails to understand how by serving the devotee Bhagavata or the book Bhagavata one gets gradual promotion on the path of devotion.

Only one who has properly grasped the transcendental knowledge from the right source by submissive hearing can properly explain the subject.
A.C. Bhaktivedanta Swami Prabhupada
One can assimilate the knowledge of the revealed scriptures only by hearing and explaining.
