Pradyumna: "Only by his implication in material activities has he become miserable, temporary and full of ignorance. This is due to vikarma. Vikarma means actions which should not be done. Therefore we must practice sādhana-bhakti, which means to offer maṅgala-ārātrika (Deity worship) in the morning, to refrain from certain material activities, to offer obeisances to the spiritual master and to follow many other rules and regulations which will be discussed here one after another. These practices will help one to become cured of madness. As a man's mental disease is cured by the directions of a psychiatrist, so this sādhana-bhakti cures the conditioned soul of his madness under the spell of māyā, material illusion."
Prabhupāda: So, as they are mentioned, the first principle is that every devotee must try to rise early in the morning. That is first business. This practice should be done first. No one should sleep more than six hours. Or, if you want to sleep more . . . but you must rise in early in the morning, at four o'clock, attend the ārātrika, maṅgala-ārātrika. Maṅgala-ārātrika means auspicious beginning of your day.
If you stand before maṅgala-ārātrika . . . in Vṛndāvana you see now, every temple, as soon as there is four o'clock, the ding-dong bell immediately begins. People can rise early in the morning, take bath in the Yamunā and visit the Deities in the temple. There is no necessity of passing M.A. examination, taking B.A. degree for devotional service. Simply you have to follow the regulative principles. Then automatically you'll become spiritualized. Very simple method. Vṛndāvana is specially meant for that purpose. Why people come to Vṛndāvana? To take the advantage. Here the atmosphere is surcharged with devotional service. We should take advantage of it.
