"Every living entity under the spell of material energy is held to be in an abnormal condition of madness. In the Śrīmad-Bhāgavatam 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 its original condition is joyful, blissful, eternal and full of knowledge, and 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-ārati 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 maya, or material illusion."
"Nārada Muni mentions this sādhana-bhakti in the Śrīmad-Bhāgavatam, Seventh Canto, First Chapter, thirtieth verse (SB 7.1.13). He says there to King Yudhiṣṭhira, 'My dear King, one has to fix his mind on Kṛṣṇa by any means.' That is called Kṛṣṇa consciousness. It is the duty of the ācārya, spiritual master, to find the ways and means for his disciple to fix his mind on Kṛṣṇa. That is the beginning of sādhana-bhakti."
