When one is situated on the neophyte platform, one cannot understand the devotional ingredients of a pure, unalloyed devotee. However, when the novice engages in devotional service — especially in Deity worship — and follows the order of a bona fide spiritual master, he is a pure devotee. Anyone can take advantage of hearing about Krsna consciousness from such a devotee and thus gradually become purified. In other words, any devotee who believes that the holy name of the Lord is identical with the Lord is a pure devotee, even though he may be in the neophyte stage. By his association, others may also become Vaisnavas.
