Every living entity under the spell of material energy is held to be in an abnormal condition of madness. In Srimad-Bhagavatam it is said, “Generally, the conditioned soul is mad, because he is always engaged in activities which are the causes of bondage and suffering.” The spirit soul in his original condition is joyful, blissful, eternal and full of knowledge. 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 sadhana-bhakti — which means to offer mangala-arati (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 become cured of madness. As a man’s mental disease is cured by the directions of a psychiatrist, so this sadhana-bhakti cures the conditioned soul of his madness under the spell of maya, material illusion.
