The appearance of consciousness after the appearance of false ego indicates that, from the beginning, material consciousness is under the mode of ignorance and that one therefore has to purify himself by purifying his consciousness. This purificatory process is called Kṛṣṇa consciousness. As soon as the consciousness is purified, the false ego disappears. Identification of the body with the self is called false identification, or false ego. Lord Caitanya confirms this in His Śikṣāṣṭaka. He states that the first result of chanting the mahā-mantra, Hare Kṛṣṇa, is that dirt is cleared from the consciousness, or the mirror of the mind, and then at once the blazing fire of material existence is over. The blazing fire of material existence is due to false ego, but as soon as the false ego is removed, one can understand his real identity. At that point he is actually liberated from the clutches of māyā. As soon as one is freed from the clutches of false ego, his intelligence also becomes purified, and then his mind is always engaged upon the lotus feet of the Supreme Personality of Godhead.
(Srimad Bhagavatam-----3:26:61-----purport).

Persons who are unknowledgeable falsely identify with gross material consciousness and are full of material designations. This body is a gift of the material nature, and one who is too much attached to the bodily consciousness is called manda, or a lazy person without understanding of spirit soul. Ignorant men think of the body as the self; they accept bodily connections with others as kinsmanship, the land in which the body is obtained is their object of worship, and they consider the formalities of religious rituals to be ends in themselves. Social work, nationalism and altruism are some of the activities for such materially designated persons. Under the spell of such designations, they are always busy in the material field; for them spiritual realization is a myth, and so they are not interested. Those who are enlightened in spiritual life, however, should not try to agitate such materially engrossed persons. Better to prosecute one's own spiritual activities silently. Such bewildered persons may be engaged in such primary moral principles of life as nonviolence and similar materially benevolent work.
(Bhagavad-Gita-----3:29-----purport).

False ego means accepting this body as oneself. When one understands that he is not his body and is spirit soul, he comes to his real ego. Ego is there. False ego is condemned, but not real ego. In the Vedic literature (Bṛhad-āraṇyaka Upaniṣad 1.4.10) it is said, ahaṁ brahmāsmi: I am Brahman, I am spirit. This "I am," the sense of self, also exists in the liberated stage of self-realization. This sense of "I am" is ego, but when the sense of "I am" is applied to this false body it is false ego. When the sense of self is applied to reality, that is real ego. There are some philosophers who say we should give up our ego, but we cannot give up our ego, because ego means identity. We ought, of course, to give up the false identification with the body.
(Bhagavad-Gita-----13:8-12-----purport).

At this point in our investigation, we may consider the following question: on the one hand we realize that all our perceptions and activities are conditioned by arrangements of material nature, yet we also ordinarily feel and say, "I am perceiving" or "I am doing." Therefore we can say that our material senses of perception and action are moving because we are identifying the self with the material body, and that the superior principle of Superself is guiding and supplying us according to our desire. By taking advantage of the guidance of Superself in the form of intelligence, we can either continue to study and to put into practice our conclusion that "I am not this body," or we can choose to remain in the false material identification, fancying ourselves to be the possessors and doers. Our freedom consists in orienting our desire either toward the ignorant, material misconception or the true, spiritual conception. We can easily attain to the true, spiritual conception by recognizing the Superself (Paramātmā) to be our friend and guide and by dovetailing our intelligence with the superior intelligence of Paramātmā.
(Srimad Bhagavatam-----2:2:35-----purport).

The first emanation from the Supreme Lord for material creation is called the mahat-tattva. The interaction of the material modes is the cause of false identification, or the sense that a living being is made of material elements. This false ego is the cause of identifying the body and mind with the soul proper. Material resources and the capacity and knowledge to work are all generated in the second term of creation, after the mahat-tattva. Jñāna indicates the senses which are sources of knowledge, and their controlling deities. Work entails the working organs and their controlling deities. All these are generated in the second creation.
(Srimad Bhagavatam-----3:10:15-----purport).

The energy of the Lord called avidyā is the bewildering factor of the conditioned souls. The material nature is called avidyā, or ignorance, but to the devotees of the Lord engaged in pure devotional service, this energy becomes vidyā, or pure knowledge. This is confirmed in Bhagavad-gītā. The energy of the Lord transforms from mahāmāyā to yogamāyā and appears to pure devotees in her real feature. The material nature therefore appears to function in three phases: as the creative principle of the material world, as ignorance and as knowledge. As disclosed in the previous verse, in the fourth creation the power of knowledge is also created. The conditioned souls are not originally fools, but by the influence of the avidyā function of material nature they are made fools, and thus they are unable to utilize knowledge in the proper channel.
By the influence of darkness, the conditioned soul forgets his relationship with the Supreme Lord and is overwhelmed by attachment, hatred, pride, ignorance and false identification, the five kinds of illusion that cause material bondage.
(Srimad Bhagavatam-----3:10:17-----purport).

Unless a living entity forgets his real identity, it is impossible for him to live in the material conditions of life. Therefore the first condition of material existence is forgetfulness of one's real identity. And by forgetting one's real identity, one is sure to be afraid of death, although a pure living soul is deathless and birthless. This false identification with material nature is the cause of false ownership of things which are offered by the arrangement of superior control. All material resources are offered to the living entity for his peaceful living and for the discharge of the duties of self-realization in conditioned life. But due to false identification, the conditioned soul becomes entrapped by the sense of false ownership of the property of the Supreme Lord.
(Srimad Bhagavatam-----3:12:2-----purport).

The false ego of identifying one's body as one's self and of claiming things possessed in relationship with this body is called māyā. In Bhagavad-gītā, Fifteenth Chapter, the Lord says, "I am sitting in everyone's heart, and from Me come everyone's remembrance and forgetfulness." Devahūti has stated that false identification of the body with the self and attachment for possessions in relation to the body are also under the direction of the Lord. Does this mean that the Lord discriminates by engaging one in His devotional service and another in sense gratification? If that were true, it would be an incongruity on the part of the Supreme Lord, but that is not the actual fact. As soon as the living entity forgets his real, constitutional position of eternal servitorship to the Lord and wants instead to enjoy himself by sense gratification, he is captured by māyā. This capture by māyā is the consciousness of false identification with the body and attachment for the possessions of the body. These are the activities of māyā, and since māyā is also an agent of the Lord, it is indirectly the action of the Lord. The Lord is merciful; if anyone wants to forget Him and enjoy this material world, He gives him full facility, not directly but through the agency of His material potency. Therefore, since the material potency is the Lord's energy, indirectly it is the Lord who gives the facility to forget Him. Devahūti therefore said, "My engagement in sense gratification was also due to You. Now kindly get me free from this entanglement."
(Srimad Bhagavatam-----3:25:10-----purport).

Kāma and lobha are the symptoms of material existence. Everyone always desires to possess something. It is said here that desire and greed are the products of false identification of oneself with the body. When one becomes free from this contamination, then his mind and consciousness also become freed and attain their original state. Mind, consciousness and the living entity exist. Whenever we speak of the living entity, this includes the mind and consciousness. The difference between conditional life and liberated life occurs when we purify the mind and the consciousness. When they are purified, one becomes transcendental to material happiness and distress.
(Srimad Bhagavatam-----3:25:16-----purport).

When one is fixed in the understanding that he is part and parcel of the Supreme Soul and that his eternal position is to serve in association with the Supreme Lord, he becomes self-realized. This position of rightly understanding oneself cuts the knot of material attraction (hṛdaya-granthi-bhedanam). Due to false ego, or false identification of oneself with the body and the material world, one is entrapped by māyā, but as soon as one understands that he is qualitatively the same substance as the Supreme Lord because he belongs to the same category of spirit soul, and that his perpetual position is to serve, one attains ātma-darśanam and hṛdaya-granthi-bhedanam, self-realization. When one can cut the knot of attachment to the material world, his understanding is called knowledge. Ātma-darśanam means to see oneself by knowledge; therefore, when one is freed from the false ego by the cultivation of real knowledge, he sees himself, and that is the ultimate necessity of human life.
(Srimad Bhagavatam-----3:26:2-----purport).
