To become desireless means not to desire anything for sense gratification. In other words, desire for becoming Kṛṣṇa conscious is actually desirelessness. To understand one's actual position as the eternal servitor of Kṛṣṇa, without falsely claiming this material body to be oneself and without falsely claiming proprietorship over anything in the world, is the perfect stage of Kṛṣṇa consciousness. One who is situated in this perfect stage knows that because Kṛṣṇa is the proprietor of everything, everything must be used for the satisfaction of Kṛṣṇa. Arjuna did not want to fight for his own sense satisfaction, but when he became fully Kṛṣṇa conscious he fought because Kṛṣṇa wanted him to fight. For himself there was no desire to fight, but for Kṛṣṇa the same Arjuna fought to his best ability. Real desirelessness is desire for the satisfaction of Kṛṣṇa, not an artificial attempt to abolish desires. The living entity cannot be desireless or senseless, but he does have to change the quality of the desires. A materially desireless person certainly knows that everything belongs to Kṛṣṇa (īśāvāsyam idaṁ sarvam ), and therefore he does not falsely claim proprietorship over anything. This transcendental knowledge is based on self-realization-namely, knowing perfectly well that every living entity is an eternal part and parcel of Kṛṣṇa in spiritual identity, and that the eternal position of the living entity is therefore never on the level of Kṛṣṇa or greater than Him. This understanding of Kṛṣṇa consciousness is the basic principle of real peace.
(Bhagavad-Gita----2:71----purport).

Renunciation without Kṛṣṇa consciousness is incomplete, as is confirmed by Śrīla Rūpa Gosvāmī in his Bhakti-rasāmṛta-sindhu (1.2.258):
prāpañcikatayā buddhyā
hari-sambandhi-vastunaḥ
mumukṣubhiḥ parityāgo
vairāgyaṁ phalgu kathyate
"When persons eager to achieve liberation renounce things related to the Supreme Personality of Godhead, thinking them to be material, their renunciation is called incomplete." Renunciation is complete when it is in the knowledge that everything in existence belongs to the Lord and that no one should claim proprietorship over anything. One should understand that, factually, nothing belongs to anyone. Then where is the question of renunciation? One who knows that everything is Kṛṣṇa's property is always situated in renunciation. Since everything belongs to Kṛṣṇa, everything should be employed in the service of Kṛṣṇa. This perfect form of action in Kṛṣṇa consciousness is far better than any amount of artificial renunciation by a sannyāsī of the Māyāvādī school.
(Bhagavad-Gita----5:2----purport).

In the Īśopaniṣad it is said that everything is related to the Supreme Brahman, or Kṛṣṇa, and thus everything belongs to Him only. One who knows perfectly well thateverything belongs to Kṛṣṇa, that He is the proprietor of everything and that, therefore, everything is engaged in the service of the Lord, naturally has nothing to do with the results of his activities, whether virtuous or sinful. Even one's material body, being a gift of the Lord for carrying out a particular type of action, can be engaged in Kṛṣṇa consciousness. It is then beyond contamination by sinful reactions, exactly as the lotus leaf, though remaining in the water, is not wet. The Lord also says in the Gītā (3.30), mayi sarvāṇi karmāṇi sannyasya: "Resign all works unto Me (Kṛṣṇa)." The conclusion is that a person without Kṛṣṇa consciousness acts according to the concept of the material body and senses, but a person in Kṛṣṇa consciousness acts according to the knowledge that the body is the property of Kṛṣṇa and should therefore be engaged in the service of Kṛṣṇa.
(Bhagavad-Gita----5:10----purport).

A Kṛṣṇa conscious person well knows that everything belongs to Kṛṣṇa, and thus he is always free from feelings of personal possession. As such, he has no hankering for anything on his own personal account. He knows how to accept things in favor of Kṛṣṇa consciousness and how to reject things unfavorable to Kṛṣṇa consciousness. He is always aloof from material things because he is always transcendental, and he is always alone, having nothing to do with persons not in Kṛṣṇa consciousness. Therefore a person in Kṛṣṇa consciousness is the perfect yogī.
(Bhagavad-Gita----6:10----purport).

Real intelligence means linking with the Supreme Personality of Godhead. When this is done, the Supreme Personality of Godhead from within gives one the real intelligence by which one can return home, back to Godhead. Intelligence in the material world is described in this verse as pramadā because in material existence the living entity falsely claims things to be his. He thinks, "I am the monarch of all I survey." This is ignorance. Actually, nothing belongs to him. Even the body and the senses do not belong to him, for they are given to him by the grace of the Lord to satisfy his different propensities through the material energy. Nothing actually belongs to the living entity, but he becomes mad after everything, claiming, "This is mine. This is mine. This is mine." Janasya moho 'yam ahaṁ mameti (S.B.5:5:8). This is called illusion. Nothing belongs to the living entity, but he claims that everything belongs to him. Lord Caitanya Mahāprabhu recommends that this false intelligence be purified (ceto-darpaṇa-mārjanam (CC.3:20:12). 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).

The forest of material existence is summarized in this Fourteenth Chapter. The word bhavāṭavī refers to the path of material existence. The merchant is the living entity who comes to the forest of material existence to try to make money for sense gratification. The six plunderers are the senses—eyes, ears, nose, tongue, touch and mind. The bad leader is diverted intelligence. Intelligence is meant for Kṛṣṇa consciousness, but due to material existence we divert all our intelligence to achieve material facilities. Everything belongs to Kṛṣṇa, the Supreme Personality of Godhead, but due to our perverted mind and senses, we plunder the property of the Lord and engage in satisfying our senses.
(Srimad Bhagavatam----5:14:46-----purport).

Since all property belongs to the Supreme Personality of Godhead, everything should be offered to the Lord, and we should take only prasāda (tena tyaktena bhuñjīthāḥ). We should not fight among ourselves to take more than we need. As Nārada said to Mahārāja Yudhiṣṭhira:
yāvad bhriyeta jaṭharaṁ
tāvat svatvaṁ hi dehinām
adhikaṁ yo 'bhimanyeta
sa steno daṇḍam arhati
"One may claim proprietorship to as much wealth as required to maintain body and soul together, but one who desires proprietorship over more than that must be considered a thief, and he deserves to be punished by the laws of nature." (S.B.7:14:8) Of course, we need to be maintained in eating, sleeping, mating and defending (āhāra-nidra-bhaya-maithuna), but since the Supreme Lord, the Personality of Godhead, has provided these necessities of life for the birds and bees, why not for mankind? There is no need for economic development; everything is provided. Therefore one should understand that everything belongs to Kṛṣṇa, and with this idea, one may take prasāda. However, if one interferes with the allotments of others, he is a thief.
(Srimad Bhagavatam----8:1:10-----purport).

The heavenly planets, the abodes of the demigods, appear to a devotee like phantasmagorias. The yogīs meditate for sense control, but for the devotee the senses appear like serpents with broken teeth. The devotee doesn’t have to control his senses, for his senses are already engaged in the Lord's service. Consequently there is no possibility that the senses will act like serpents. In the material condition, the senses are as strong as poisonous snakes. But when the senses are engaged in the Lord's service, they are like poisonous snakes with their fangs removed, and so they are no longer dangerous. The entire world is a replica of Vaikuṇṭha for the devotee because he has no anxiety. He sees that everything belongs to Kṛṣṇa, and he does not want to enjoy anything for himself. He does not even aspire for the position of Lord Brahmā or Indra. He simply wants to engage everything in the service of the Lord; therefore he has no problem. He stands in his original constitutional position. All this is possible when one receives Śrī Caitanya Mahāprabhu's merciful glance.
(Sri Caitanya Caritamrta-----2:10:177----purport).

Whatever charity one gives to a brāhmaṇa goes to Kṛṣṇa, who says in the Bhagavad-gītā (9.27):
yat karoṣi yad aśnāsi yaj juhoṣi dadāsi yat
yat tapasyasi kaunteya tat kuruṣva mad-arpaṇam
"Whatever you do, whatever you eat, whatever you offer or give away, and whatever austerities you perform—do that, O son of Kuntī, as an offering to Me." Everything actually belongs to Kṛṣṇa, but so-called civilized men unfortunately think that everything belongs to them. This is the mistake of materialistic civilization. The prostitute (veśyā) had earned money by questionable means, and therefore Haridāsa Ṭhākura advised her to distribute to the brāhmaṇas whatever she possessed. When Śrīla Rūpa Gosvāmī retired from family life, he distributed fifty percent of his income to the brāhmaṇas and Vaiṣṇavas. A brāhmaṇa knows what the Absolute Truth is, and a Vaiṣṇava, knowing the Absolute Truth, acts on behalf of the Absolute Truth, the Supreme Personality of Godhead. Generally one earns money by many questionable means. Therefore at some time one should retire and distribute whatever one has to the brāhmaṇas and Vaiṣṇavas who engage in devotional service by preaching the glories of the Supreme Personality of Godhead.
