When we are materially contaminated, we are called conditioned. False consciousness is exhibited under the impression that I am a product of material nature. This is called false ego. One who is absorbed in the thought of bodily conceptions cannot understand his situation. Bhagavad-gītā was spoken to liberate one from the bodily conception of life, and Arjuna put himself in this position in order to receive this information from the Lord. One must become free from the bodily conception of life; that is the preliminary activity for the transcendentalist. One who wants to become free, who wants to become liberated, must first of all learn that he is not this material body. Mukti, or liberation, means freedom from material consciousness.
(Bhagavad-Gita---introduction).

There are two kinds of sva-dharmas, specific duties. As long as one is not liberated, one has to perform the duties of his particular body in accordance with religious principles in order to achieve liberation. When one is liberated, one's sva-dharma—specific duty—becomes spiritual and is not in the material bodily concept. In the bodily conception of lifethere are specific duties for the brāhmaṇas and kṣatriyas respectively, and such duties are unavoidable. Sva-dharma is ordained by the Lord, and this will be clarified in the Fourth Chapter. On the bodily plane sva-dharma is called varṇāśrama-dharma, or man's steppingstone for spiritual understanding. Human civilization begins from the stage of varṇāśrama-dharma, or specific duties in terms of the specific modes of nature of the body obtained. Discharging one's specific duty in any field of action in accordance with the orders of higher authorities serves to elevate one to a higher status of life.
(Bhagavad-Gita----2:31----purport).

I may either be a brāhmaṇa, kṣatriya, vaiśya or whatever-in any case, this life is temporary. But although life is temporary and we do not know what we are going to be in the next life, by the spell of this illusory energy we consider ourselves in terms of this bodily conception of life, and we thus think that we are American, Indian, Russian, or brāhmaṇa. Hindu, Muslim, etc. And if we become entangled with the modes of material nature, then we forget the Supreme Personality of Godhead who is behind all these modes. So Lord Kṛṣṇa says that living entities deluded by these three modes of nature do not understand that behind the material background is the Supreme Personality of Godhead.
(Bhagavad-Gita----7:13----purport).

The mundane qualities do not allow a living entity to understand his real position. The qualities of both ignorance and passion strongly bind one to the illusory bodily conception of the self. The best among the fools who are thus deluded are those who engage in altruistic activities under the spell of the material mode of passion. Bhagavad-gītā, which is direct kṛṣṇa-kathā, gives humanity the elementary lesson that the body is perishable and that the consciousness which is spread throughout the body is imperishable. The conscious being, the imperishable self, is eternally existent and cannot be killed under any circumstances, even after the dissolution of the body. Anyone who misunderstands this perishable body to be the self and who works for it in the name of sociology, politics, philanthropy, altruism, nationalism or internationalism, under the false plea of the bodily conception of life, is certainly a fool and does not know the implications of reality and unreality.
(Srimad Bhagavatam----3:5:11----purport).

In the material world, we manufacture many things for our material comfort simply by hearing. They are already there, but just by hearing, one can transform them. If we want to build a very high skyscraper, this does not mean that we have to create it. The materials for the skyscraper—wood, metal, earth, etc.—are already there, but we make our intimate relationship with those already created material elements by hearing how to utilize them. Modern economic advancement for creation is also a product of hearing, and similarly one can create a favorable field of spiritual activities by hearing from the right source. Arjuna was a gross materialist in the bodily conception of life and was suffering from the bodily concept very acutely. But simply by hearing, Arjuna became a spiritualized, Kṛṣṇa conscious person. Hearing is very important, and that hearing is produced from the sky. By hearing only can we make proper use of that which already exists. The principle of hearing to properly utilize preconceived materials is applicable to spiritual paraphernalia as well. We must hear from the proper spiritual source.
(Srimad Bhagavatam----3:26:32----purport).

Māyā means "illusion," or that which is actually not. In the material world, everyone is identifying with his body. This false egoistic consciousness of "I am this body" at once develops after the child comes out of the womb. The mother and other relatives are awaiting the child, and as soon as he is born, the mother feeds him, and everyone takes care of him. The living entity soon forgets his position and becomes entangled in bodily relationships. The entire material existence is entanglement in this bodily conception of life. Real knowledge means to develop the consciousness of "I am not this body. I am spirit soul, an eternal part and parcel of the Supreme Lord." Real knowledge entails renunciation, or nonacceptance of this body as the self.
(Srimad Bhagavatam----3:31:20----purport).

As long as one is too much absorbed in the bodily conception of life, he becomes interested in many different processes of self-realization, such as the mystic yoga system or the system utilizing the speculative empiric methods. However, when one understands that the ultimate goal of life is to approach Kṛṣṇa, he realizes Kṛṣṇa within everyone's heart and therefore helps everyone who is interested in Kṛṣṇa consciousness. Actually the perfection of life depends on one's inclination to hear about Kṛṣṇa. It is therefore mentioned in this verse: yāvad gadāgraja-kathāsu ratiṁ na kuryāt. Unless one becomes interested in Kṛṣṇa, in His pastimes and activities, there is no question of liberation by means of yoga practice or speculative knowledge.
(Srimad Bhagavatam----3:32:12----purport).

Every living entity is purañjana. The word puram means "within this body, within this form," and jana means "living entity." Thus everyone is purañjana. Every living entity is supposed to be the king of his body because the living entity is given full freedom to use his body as he likes. He usually engages his body for sense gratification, because one who is in the bodily conception of life feels that the ultimate goal of life is to serve the senses. This is the process of karma-kāṇḍa. One who has no inner knowledge, who does not know that he is actually the spirit soul living within the body, who is simply enamored by the dictation of the senses, is called a materialist. A materialistic person interested in sense gratification can be called a purañjana. Because such a materialistic person utilizes his senses according to his whims, he may also be called a king. An irresponsible king takes the royal position to be his personal property and misuses his treasury for sense gratification.
(Srimad Bhagavatam----4:25:10----purport).

One who wastes his life simply by committing sinful activities in youth immediately becomes disappointed and disillusioned when the brief period of youth is over. The material enjoyments of youth are especially pleasing to a person who has no spiritual training. If one is trained only according to the bodily conception of life, he simply leads a disappointed life because bodily sense enjoyment finishes within forty years or so. After forty years, one simply leads a disillusioned life because he has no spiritual knowledge. For such a person, the expiration of youth occurs in half a moment.
(Srimad Bhagavatam----4:27:5----purport).

The living entity enters the material creation with the aid of the five elements—earth, water, fire, air and ether—and thus his body is formed. Although the living entity is working from within, he is nonetheless unknown. The living entity enters the material creation, but because he is bewildered by the material energy, he appears to be hidden. Thebodily conception of life is prominent because of ignorance (nāvabudhyate).
(Srimad Bhagavatam----4:28:58----purport).
