Attachment cannot be killed; it has simply to be transferred. Attachment for material things is called material consciousness, and attachment for Kṛṣṇa or His devotee is called Kṛṣṇa consciousness. Consciousness, therefore, is the platform of attachment. It is clearly stated here that when we simply purify the consciousness from material consciousness to Kṛṣṇa consciousness, we attain liberation.
(Srimad Bhagavatam-----3:25:20-----purport).

The forgetful living entity can be compared to a man who is under the influence of disease and has become mad or to a man haunted by ghosts, who acts without control and yet thinks himself to be in control. Under the influence of material nature, the conditioned soul becomes absorbed in material consciousness.
(Srimad Bhagavatam-----3:26:6-----purport).

Actually, the soul in his pure state of existence should be in Kṛṣṇa consciousness. When a person is not acting in Kṛṣṇa consciousness, he is understood to be acting inmaterial consciousness. Consciousness cannot be killed, for the symptom of the living entity is consciousness. The material consciousness simply has to be purified.
(Srimad Bhagavatam-----3:26:6-----purport).

One becomes liberated by accepting Kṛṣṇa, or the Supreme Lord, as master and by changing the mode of consciousness from material consciousness to Kṛṣṇa consciousness.
(Srimad Bhagavatam-----3:26:6-----purport).

Material consciousness is the cause of one's conditional life, in which conditions are enforced upon the living entity by the material energy. Although the spirit soul does not do anything and is transcendental to such activities, he is thus affected by conditional life.
(Srimad Bhagavatam-----3:26:7-----Translation).

Persons infatuated by material consciousness are very intelligent in discovering things for material comforts, but they have no access to understanding the spirit soul and spiritual life. Therefore, if anyone wants to advance in spiritual life, he has to come back to the platform of purified desire, the purified desire for devotional service.
(Srimad Bhagavatam-----3:26:31-----purport).

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.
(Srimad Bhagavatam-----3:26:61-----purport).

One should be situated in the transcendental position, beyond the stages of material consciousness, and should be aloof from all other conceptions of life. Thus realizing freedom from false ego, one should see his own self just as he sees the sun in the sky.
(Srimad Bhagavatam-----3:27:10-----translation).

In the material world the activities of the mind are acceptance and rejection. As long as the mind is in material consciousness, it must be forcibly trained to accept meditation on the Supreme Personality of Godhead, but when one is actually elevated to loving the Supreme Lord, the mind is automatically absorbed in thought of the Lord.
(Srimad Bhagavatam-----3:28:31-----purport).

The Personality of Godhead said: As a mass of clouds does not know the powerful influence of the wind, a person engaged in material consciousness does not know the powerful strength of the time factor, by which he is being carried.
(Srimad Bhagavatam-----3:30:1-----translation).

The main function of the time factor, which is a representative of the Supreme Personality of Godhead, is to destroy everything. The materialists, in material consciousness, are engaged in producing so many things in the name of economic development. They think that by advancing in satisfying the material needs of man they will be happy, but they forget that everything they have produced will be destroyed in due course of time.
(Srimad Bhagavatam-----3:30:2-----purport).

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. In the Śrīmad-Bhāgavatam also the definition of liberation is given. Muktir hitvānyathā-rūpaṁ svarūpeṇa vyavasthitiḥ: (S.B.2:10:6) mukti means liberation from the contaminated consciousness of this material world and situation in pure consciousness.
(Bhagavad-Gita-----introduction).

What is this consciousness? This consciousness is "I am." Then what am I? In contaminated consciousness "I am" means "I am the lord of all I survey. I am the enjoyer." The world revolves because every living being thinks that he is the lord and creator of the material world. Material consciousness has two psychic divisions. One is that I am the creator, and the other is that I am the enjoyer. But actually the Supreme Lord is both the creator and the enjoyer, and the living entity, being part and parcel of the Supreme Lord, is neither the creator nor the enjoyer, but a cooperator. He is the created and the enjoyed.
(Bhagavad-Gita-----introduction).

By development of Kṛṣṇa consciousness one can know that everything has its use in the service of the Lord. Those who are without knowledge of Kṛṣṇa consciousness artificially try to avoid material objects, and as a result, although they desire liberation from material bondage, they do not attain to the perfect stage of renunciation. Their so-called renunciation is called phalgu, or less important. On the other hand, a person in Kṛṣṇa consciousness knows how to use everything in the service of the Lord; therefore he does not become a victim of material consciousness. For example, for an impersonalist, the Lord, or the Absolute, being impersonal, cannot eat. Whereas an impersonalist tries to avoid good eatables, a devotee knows that Kṛṣṇa is the supreme enjoyer and that He eats all that is offered to Him in devotion. So, after offering good eatables to the Lord, the devotee takes the remnants, called prasādam.
(Bhagavad-Gita-----2:63-----purport).

Two persons, one in Kṛṣṇa consciousness and the other in material consciousness, working on the same level, may appear to be working on the same platform, but there is a wide gulf of difference in their respective positions.
(Bhagavad-Gita-----3:27-----purport).

The person in material consciousness is convinced by false ego that he is the doer of everything. He does not know that the mechanism of the body is produced by material nature, which works under the supervision of the Supreme Lord. The materialistic person has no knowledge that ultimately he is under the control of Kṛṣṇa.
(Bhagavad-Gita-----3:27-----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.
(Bhagavad-Gita-----3:29-----purport).

In material consciousness, the senses are engaged in sense gratification, but in Kṛṣṇa consciousness the senses are engaged in the satisfaction of Kṛṣṇa's senses. Therefore, the Kṛṣṇa conscious person is always free, even though he appears to be engaged in affairs of the senses.
(Bhagavad-Gita-----5:8-9-----purport).

The constitutional position of the living entity is different from the position he takes in the material world. In material consciousness his nature is to try to be the lord of matter, but in spiritual consciousness, Kṛṣṇa consciousness, his position is to serve the Supreme.
(Bhagavad-Gita-----8:3-----purport).

When the living entity is in material consciousness, he has to take on various bodies in the material world. That is called karma, or varied creation by the force of material consciousness.
(Bhagavad-Gita-----8:3-----purport).

Knowledge and development of knowledge mean understanding oneself in Kṛṣṇa consciousness. We are being led by material consciousness, but as soon as we transfer all consciousness to Kṛṣṇa's activities and realize that Kṛṣṇa is everything, then we attain real knowledge.
(Bhagavad-Gita-----13:19-----purport).

Unless one is situated in Kṛṣṇa consciousness, his material consciousness will oblige him to transfer from one body to another because he has material desires since time immemorial. But he has to change that conception. That change can be effected only by hearing from authoritative sources.
(Bhagavad-Gita-----13:22-----purport).

As soon as one is fully Kṛṣṇa conscious it is to be understood that one is in his pure, original constitutional position. This state of existence is called śuddha-sattva, which means that it is transcendental to the material qualities. Since this śuddha-sattva existence is under the direct action of the internal potency, in this state the activities of material consciousness stop.
(Srimad Bhagavatam-----4:3:23-----purport).

If a particular part of the body is diseased, the whole attention of the body goes to that part. Similarly, devotees care for any person who is forgetful of Kṛṣṇa and therefore in material consciousness. The equal vision of the devotee is that he works to get all living entities back home, back to Godhead.
(Srimad Bhagavatam-----4:7:53-----purport).

A blazing fire is visible by its exhibition of heat and light; similarly, when the living entity within the heart becomes enlightened with full spiritual knowledge and detached from the material world, he burns up his material covering of the five elements—earth, water, fire, air and sky—and becomes free from the five kinds of material attachments, namely ignorance, false egoism, attachment to the material world, envy and absorption in material consciousness.
(Srimad Bhagavatam-----4:22:56-----purport).

By this incident we can understand that when a man is aggressive and begins to woo a woman, the woman becomes attracted to the man. This process is described in the Bhāgavatam (5.5.8) as puṁsaḥ striyā mithunī-bhāvam etam. This attraction is enacted on the platform of sexual life. Thus the sex impulse is the platform of material engagement. This conditional life, the platform of material sense enjoyment, is the cause of forgetfulness of spiritual life. In this way a living entity's original Kṛṣṇa consciousness becomes covered or converted into material consciousness. Thus one engages in the business of sense gratification.
(Srimad Bhagavatam-----4:25:32-----purport).

When the mirror of intelligence is polished, the real activities of the living entity begin. This means that when a person comes to the platform of Kṛṣṇa consciousness, his real intelligence acts. At that time he knows that everything belongs to Kṛṣṇa and nothing belongs to him. As long as one thinks that everything belongs to him, he is in material consciousness, and when he knows perfectly that everything belongs to Kṛṣṇa, he is in Kṛṣṇa consciousness.
(Srimad Bhagavatam-----4:29:5-----purport).

A person engaged in devotional service must be free from material motives. In this Kṛṣṇa consciousness movement, one's consciousness must be changed. If consciousness is aimed toward material enjoyment, it is material consciousness, and if it is aimed toward serving Kṛṣṇa, it is Kṛṣṇa consciousness.
(Nectar of Instruction).

The body is important as long as it has consciousness. Without consciousness, the body is merely a lump of matter. Therefore, to return home, back to Godhead, one must change his consciousness from material consciousness to Kṛṣṇa consciousness.
(Srimad Bhagavatam-----7:15:41-----purport).
