The summary is that one has to, first of all, seek the association of pure devotees who not only are learned in the Vedanta but are self-realized souls and unalloyed devotees of Lord Sri Krsna, the Personality of Godhead. In that association, the neophyte devotees must render loving service physically and mentally without reservation. This service attitude will induce the great souls to be more favorable in bestowing their mercy, which injects the neophyte with all the transcendental qualities of the pure devotees. Gradually this is developed into a strong attachment to hearing the transcendental pastimes of the Lord, which makes him able to catch up the constitutional position of the gross and subtle bodies and beyond them the knowledge of pure soul and his eternal relation with the Supreme Soul, the Personality of Godhead. After the relation is ascertained by establishment of the eternal relation, pure devotional service to the Lord begins gradually developing into perfect knowledge of the Personality of Godhead beyond the purview of impersonal Brahman and localized Paramatma. By such purusottama-yoga, as it is stated in the Bhagavad-gita, one is made perfect even during the present corporeal existence, and one exhibits all the good qualities of the Lord to the highest percentage. Such is the gradual development by association of pure devotees.
