The soul's activity becomes adulterated in contact with matter, and as such the diseased activities are expressed in the form of lust, desire, hankering, inactivity, foolishness and sleep. The effect of devotional service becomes manifest by complete elimination of these effects of passion and ignorance. The devotee is fixed at once in the mode of goodness, and he makes further progress to rise to the position of Vāsudeva, or the state of unmixed sattva, or śuddha-sattva. Only in this śuddha-sattva state can one always see Kṛṣṇa eye to eye by dint of pure affection for the Lord.
(SRIMAD BHAGAVATAM-------1:12:19-------PURPORT).

The Lord is so merciful that He Himself descends to take the fallen souls back home to the kingdom of Godhead, where the erotic principles of Godhead are eternally relished in their real form, distinct from the perverted sexual love so much adored and indulged in by the fallen souls in their diseased condition. The reason the Lord displays the rāsa-līlā is essentially to induce all the fallen souls to give up their diseased morality and religiosity, and to attract them to the kingdom of God to enjoy the reality. A person who actually understands what the rāsa-līlā is will certainly hate to indulge in mundane sex life. For the realized soul, hearing the Lord's rāsa-līlā through the proper channel will result in complete abstinence from material sexual pleasure.
(SRI CAITANYA CARITAMRTA------1:4:30---------PURPORT).

Śrīmad-Bhāgavatam is the summum bonum remedy for suffering humanity in the clutches of māyā. Śrīla Vyāsadeva therefore first of all diagnosed the actual disease of the conditioned souls, i.e., their being illusioned by the external energy. He also saw the perfect Supreme Being, from whom illusory energy is far removed, though He saw both the diseased conditioned souls and also the cause of the disease.
(SRIMAD BHAGAVATAM-------1:7:5-------PURPORT).

Murāri Gupta could treat both bodily and spiritual disease because he was a physician by profession and a great devotee of the Lord in terms of spiritual advancement. This is an example of service to humanity. Everyone should know that there are two kinds of diseases in human society. One disease, which is called adhyātmika, or material disease, pertains to the body, but the main disease is spiritual. The living entity is eternal, but somehow or other, when in contact with the material energy, he is subjected to the repetition of birth, death, old age and disease. The physicians of the modern day should learn from Murāri Gupta. Although modern philanthropic physicians open gigantic hospitals, there are no hospitals to cure the material disease of the spirit soul. The Kṛṣṇa consciousness movement has taken up the mission of curing this disease, but people are not very appreciative because they do not know what this disease is. A diseased person needs both proper medicine and a proper diet, and therefore the Kṛṣṇa consciousness movement supplies materially stricken people with the medicine of the chanting of the holy name, or the Hare Kṛṣṇa mahā-mantra, and the diet of prasādam. There are many hospitals and medical clinics to cure bodily diseases, but there are no such hospitals to cure the material disease of the spirit soul. The centers of the Kṛṣṇa consciousness movement are the only established hospitals that can cure man of birth, death, old age and disease.
(SRI CAITANYA CARITAMRTA------1:10:51---------PURPORT).

Because they are between the internal and external potencies, the eternally transcendental living entities are called the marginal potency of the Lord. Factually, the living entities are not meant to be so conditioned by material energy, but due to their being affected by the false sense of lording it over the material energy, they come under the influence of such potency and thus become conditioned by the three modes of material nature. This external energy of the Lord covers up the pure knowledge of the living entities eternally existing with Him, but the covering is so constant that it appears that the conditioned soul is eternally ignorant. Such is the wonderful action of māyā, or external energy manifested as if materially produced. By the covering power of the material energy, the material scientist cannot look beyond the material causes, but factually, behind the material manifestations, there are adhibhūta, adhyātma and adhidaiva actions, which the conditioned soul in the mode of ignorance cannot see. The adhibhūta manifestation entails repetitions of births and deaths with old age and diseases, the adhyātma manifestation conditions the spirit soul, and the adhidaiva manifestation is the controlling system. These are the material manifestations of cause and effect and the sense of responsibility of the conditioned actors. They are, after all, manifestations of the conditioned state, and the human being's freedom from such a conditioned state is the highest perfectional attainment.
(SRIMAD BHAGAVATAM-------2:5:19-------PURPORT).

Due to being conditioned by the external energy, the conditioned soul within this material world gets two kinds of bodies—a gross material body and a subtle material body composed of mind, intelligence and ego. Due to the gross and subtle bodies, he is subjected to the threefold miseries (ādhyātmika, ādhibhautika and ādhidaivika), miseries arising from the body and mind, other living entities and natural disturbances caused by demigods from higher planetary systems. The conditioned soul subjected to the threefold material miseries is ceaselessly kicked by māyā, and this is his disease. If by chance he meets a saintly person who works on Kṛṣṇa's behalf to deliver conditioned souls, and if he agrees to abide by his order, he can gradually approach the Supreme Personality of Godhead, Kṛṣṇa.
(SRIMAD BHAGAVATAM-------2:22:14-15-------PURPORT).

Kṛṣṇa's separated expanded forms are the living entities, who are classified according to which of the Lord's energies they are under. They are divided into two classes—eternally liberated and eternally conditioned. Eternally liberated living entities never come into contact with the material nature, and therefore they do not have any experience of material life. They are eternally engaged in Kṛṣṇa consciousness, or devotional service to the Lord, and they are counted among the associates of Kṛṣṇa. Their pleasure, the only enjoyment of their life, is derived from rendering transcendental loving service to Kṛṣṇa.
On the other hand, those who are eternally conditioned are always divorced from the transcendental loving service of Kṛṣṇa and are thus subjected to the threefold miseries of material existence. On account of the conditioned soul's eternal attitude of separation from Kṛṣṇa, the spell of the material energy awards him two kinds of bodies—the gross body, consisting of five elements, and the subtle body, consisting of mind, intelligence and ego. Being covered by these two bodies, the conditioned soul eternally suffers the pangs of material existence, known as the threefold miseries. He is also subjected to six enemies (lust, anger, etc.). Such is the everlasting disease of the conditioned soul.

(TEACHINGS OF LORD CAITANYA).

It is clearly said here that the principle of service was generated from the legs of the Lord for the sake of perfecting the religious process, but this transcendental service is different from the idea of service in the material world. In the material world, no one wants to be a servant; everyone wants to become the master because false mastership is the basic disease of the conditioned soul. The conditioned soul in the material world wants to lord it over others. Illusioned by the external energy of the Lord, he is forced to become a servant of the material world. That is the real position of the conditioned soul. The last snare of the illusory, external energy is the conception of becoming one with the Lord, and due to this conception the illusioned soul remains in the bondage of material energy, falsely thinking himself a liberated soul and "as good as Nārāyaṇa."
(SRIMAD BHAGAVATAM-------3:6:33-------PURPORT).

Every living entity under the spell of material energy is held to be in an abnormal condition of madness. In 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." 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 sādhana-bhakti—which means to offer maṅgala-ārati (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 sādhana-bhakti cures the conditioned soul of his madness under the spell of māyā, material illusion.
(NECTAR OF DEVOTION).

In Bhagavad-gītā it is said that at the time of death one will be absorbed in the thoughts which he cultivated during his lifetime. A person who had no other idea than to properly maintain his family members must have family affairs in his last thoughts. That is the natural sequence for a common man. The common man does not know the destiny of his life; he is simply busy in his flash of life, maintaining his family. At the last stage, no one is satisfied with how he has improved the family economic condition; everyone thinks that he could not provide sufficiently. Because of his deep family affection, he forgets his main duty of controlling the senses and improving his spiritual consciousness. Sometimes a dying man entrusts the family affairs to either his son or some relative, saying, "I am going. Please look after the family." He does not know where he is going, but even at the time of death he is anxious about how his family will be maintained. Sometimes it is seen that a dying man requests the physician to increase his life at least for a few years so that the family maintenance plan which he has begun can be completed. These are the material diseases of the conditioned soul. He completely forgets his real engagement—to become Kṛṣṇa conscious—and is always serious about planning to maintain his family, although he changes families one after another.
(SRIMAD BHAGAVATAM-------3:30:18-------PURPORT).

Persons bereft of these qualities are not eligible to discuss spiritual topics. The false logicians mistake the above-mentioned qualities, which are meant to lead the conditioned soul to liberation, for mundane qualities acquired as a result of transformations of the mind, such as lust, anger, and hate. But factually, the above-mentioned qualities represent spiritual knowledge. Even if one accepts the false logicians' argument that the qualities Lord Kṛṣṇa enumerates in the Gītā as prerequisites for absolute knowledge are mental transformations, still we cannot agree that these transformations are equivalent to such qualities as lust, greed, anger, and illusion, which result from gross ignorance. One kind ofmental transformation drags the soul down to depravity, whereas the other redeems the soul from doom. Both disease and medicine are products of material nature, yet one pushes a man toward the jaws of death, while the other saves him from destruction. So one must avoid becoming the laughing-stock of society by accepting the foolish theory of yatA mata, tata path—"All ways lead to the Truth"—and on this basis professing that the medicine and the disease are one and the same.
(RENUNCIATION THROUGH WISDOM).

Diseased and conditioned, the living entity transmigrates all over the universe. Sometimes he is situated in the upper planetary system, and sometimes he travels in the lower planetary system. In this way he leads his diseased, conditioned life. His disease can be cured only when he meets and follows the expert physician, the bona fide spiritual master. When the conditioned soul faithfully follows the instructions of a bona fide spiritual master, his material disease is cured, he is promoted to the liberated stage, and he again attains to the devotional service of Kṛṣṇa and goes back home, back to Kṛṣṇa.
(TEACHINGS OF LORD CAITANYA).

Foolish people do not know that every individual soul is responsible for his own actions and reactions in life. As long as a living entity in the form of a child or boy is innocent, it is the duty of the father and mother to lead him into a proper understanding of the values of life. When a child is grown, it should be left up to him to execute the duties of life properly. The parent, after his death, cannot help his child. A father may leave some estate for his children's immediate help, but he should not be overly absorbed in thoughts of how his family will survive after his death. This is the disease of the conditioned soul. Not only does he commit sinful activities for his own sense gratification, but he accumulates great wealth to leave behind so that his children may also gorgeously arrange for sense gratification.
(SRIMAD BHAGAVATAM-------4:28:22-------PURPORT).

The impersonalists are obsessed with the idea that the Supreme Being is impersonal and that the final goal is to merge into that Brahman existence. Naturally the Lord does not object. If a patient wants to end his disease by ending his life, then who will suffer but him? The more intelligent person will surely want to cure his disease without ending his life, and to that end he will strive to regain his original health. Similarly, the soul infected with the material disease should want to return to his pure, original state without annihilating his individual identity. Lord Kṛṣṇa saves such persons from the jaws of the demoniac conception of trying to become one with God. It is suicidal for the spirit soul to attempt to lose his inherent individuality. The happiness the impersonalist experiences by disentangling himself from the knots of material existence is automatically available to the Lord's devotee as a by-product of devotional service.
(RENUNCIATION THROUGH WISDOM).

If a bona fide listener hears of Kṛṣṇa's pastimes with the gopīs, which seem to be lusty affairs, the lusty desires in his heart, which constitute the heart disease of the conditioned soul, will be vanquished, and he will become a most exalted devotee of the Lord. If one who hears of the gopīs' lusty behavior with Kṛṣṇa becomes free from lusty desires, certainly the gopīs who approached Kṛṣṇa became free from all such desires. Similarly, Śiśupāla and others who were very much envious of Kṛṣṇa and who constantly thought of Kṛṣṇa became free from envy. Nanda Mahārāja and mother Yaśodā were fully absorbed in Kṛṣṇa consciousness because of affection. When the mind is somehow or other fully absorbed in Kṛṣṇa, the material part is very soon vanquished, and the spiritual part—attraction to Kṛṣṇa—becomes manifest. This indirectly confirms that if one thinks of Kṛṣṇa enviously, simply because of thinking of Kṛṣṇa he becomes free from all sinful reactions and thus becomes a pure devotee.
