"The introspective neophyte rejects demigod worship and worships only Krsna, though with certain material motivations. He is inexperienced in the understanding of the spiritual identities of himself, Lord Krsna, and the pure devotee of the Lord. Though he is simple and naive, he is not offensive; he is just preoccupied with himself. Therefore, the neophytes are not considered to be pure Vaisnavas, though they are certainly to be seen as vaisnava- praya or resembling Vaisnavas.

"The intermediate introspective jiva, or the madhyama, is a pure devotee and is very firmly situated in devotion. As for the uttama or advanced introspective jiva, so much can be said about him: he has reached a state of perfect equanimity. One cannot become truly introspective without first being situated in knowledge of the equal position of the holy name and Krsna Himself. The introspective jiva automatically has a single-minded faith in the Supreme Lord; hence, he is entitled to chant the holy name purely.

Although both Buddhist and modern no-self philosophers contend that there is no self, Buddhist followers do not tend toward hedonism.

Advancement in hearing, chanting, and remembering

"The order of discipline or sadhana-krama is as follows: The introspective devotee must at first discard all the ten offenses and simply meditate on the holy name, trying to chant constantly. He should distinctly pronounce the holy name and meditate upon the transcendental sound vibration. When his chanting is clear, steady and blissful he should try and meditate on the Syamasundara form of the Lord. With chanting beads in hand, his chanting and meditation should seek out the transcendental form of the holy name. He will indeed see with spiritual vision the real meaning the name represents.

"Another method he may employ to see this form is to sit in front of the Deities, drink the beautiful form of the Lord with his eyes and meditate upon the holy name. Even after reaching the stage where the holy name and the form of the Lord become one, he must try to remember the transcendental qualities of Lord Krsna. The holy name and the qualities of Krsna must merge through consistant chanting.
