The more one hears about Kṛṣṇa, the more one becomes enlightened and detached from everything that draws the mind away from Kṛṣṇa. By detaching the mind from activities not devoted to the Lord, one can very easily learn vairāgya. Vairāgya means detachment from matter and engagement of the mind in spirit. Impersonal spiritual detachment is more difficult than attaching the mind to the activities of Kṛṣṇa. This is practical because by hearing about Kṛṣṇa one becomes automatically attached to the Supreme Spirit. This attachment is called pareśānubhūti, spiritual satisfaction. It is just like the feeling of satisfaction a hungry man has for every morsel of food he eats. The more one eats while hungry, the more one feels satisfaction and strength. Similarly, by discharge of devotional service one feels transcendental satisfaction as the mind becomes detached from material objectives.
(Bhagavad-Gita-----6:35-----purport).

As soon as one engages in such serious devotional service of the Lord, naturally the propensity to falsely claim lordship over material nature disappears. That detachment is called vairāgya. Instead of being absorbed in so-called material lordship, one engages in Kṛṣṇa consciousness; that is control of consciousness.
(Srimad Bhagavatam-----3:27:5-----purport).

The qualification of bhakti, or devotional service to the Lord, is that the devotee should be free from all material contaminations and desires. This freedom is calledvairāgya, or renouncement of material desires.
(Srimad Bhagavatam-----3:13:39-----purport).

As the contamination of the germs of a particular disease can influence a weaker person, similarly the influence of material nature, or illusory energy, can act on the weaker, or conditioned, soul but not on the liberated soul. Self-realization is the position of the liberated state. One understands his constitutional position by knowledge and vairāgya, renunciation. Without knowledge, one cannot have realization. The realization that one is the infinitesimal part and parcel of the Supreme Spirit makes him unattached to material, conditional life. That is the beginning of devotional service.
(Srimad Bhagavatam-----3:25:18-----purport).

As soon as one engages in such serious devotional service of the Lord, naturally the propensity to falsely claim lordship over material nature disappears. That detachment is called vairāgya. Instead of being absorbed in so-called material lordship, one engages in Kṛṣṇa consciousness; that is control of consciousness.
(Srimad Bhagavatam-----3:27:5-----purport).

Devotional service in Kṛṣṇa consciousness cannot be performed blindly due to material emotion or mental concoction. It is specifically mentioned here that one has to perform devotional service in full knowledge by visualizing the Absolute Truth. We can understand about the Absolute Truth by evolving transcendental knowledge, and the result of such transcendental knowledge will be manifested by renunciation. That renunciation is not temporary or artificial, but is very strong. It is said that development of Kṛṣṇa consciousness is exhibited by proportionate material detachment, or vairāgya.
(Srimad Bhagavatam-----3:27:22-----purport).

Rūpa Gosvāmī advises that if one renounces anything which could be applied in the service of the Lord and does not use it for that purpose, that is called phalgu-vairāgya, insufficient or false renunciation. Everything belongs to the Supreme Personality of Godhead; therefore everything can be engaged in the service of the Lord; nothing should be used for one's sense gratification. That is real renunciation. Nor should one unnecessarily increase the necessities of the body. We should be satisfied with whatever is offered and supplied by Kṛṣṇa without much personal endeavor. We should spend our time executing devotional service in Kṛṣṇa consciousness. That is the solution to the problem of life and death.
(Srimad Bhagavatam-----3:31:47-----purport).

Because a devotee accepts everything in spiritual vision, he is equipoised; that is the symptom of his being elevated to the transcendental position. He automatically attains detachment, vairāgya, then jñāna, knowledge, and then actual transcendental knowledge.
(Srimad Bhagavatam-----3:32:24-----purport).

Bhakti, or devotional service, is characterized by vairāgya and jñāna. Jñāna refers to understanding that one is not his body, and vairāgya means disinterest in sense gratification.
(Srimad Bhagavatam-----4:21:32-----purport).

Knowledge and the spirit of renunciation (jñāna-vairāgya) are the ultimate goal of life. Without knowledge, one cannot become detached from material enjoyment, and without being detached from material enjoyment, one cannot make spiritual advancement.
(Srimad Bhagavatam-----4:25:7-----purport).

If one engages in devotional service from the beginning of life, he easily attains vairāgya-vidyā, or asakti, detachment, and becomes jitendriya, the controller of his senses.
(Srimad Bhagavatam-----7:6:9-----purport).

One who is firm in yoga is constantly engaged in Kṛṣṇa consciousness in all his activities. Śrī Rūpa Gosvāmī advises, anāsaktasya viṣayān yathārham upayuñjataḥ: one should be unattached in material affairs and do everything in Kṛṣṇa consciousness. By this system, which is called yukta-vairāgya, one attains perfection.
(Bhagavad-Gita-----8:27-----purport).
