One who engages in full devotional service, unfailing in all circumstances, at once transcends the modes of material nature and thus comes to the level of Brahman.
(Bhagavad-Gita---14:26---translation).
One who engages in full devotional service and who does not fall down in any circumstance at once transcends the modes of material nature.
(Srimad Bhagavatam----4:21:42----purport).
"One who engages in full devotional service, who does not fall down in any circumstance, at once transcends the modes of material nature and thus comes to the spiritual platform." By engaging one in devotional service, the Kṛṣṇa consciousness movement keeps one always transcendental to anger, greed, lust, envy and so forth. One must perform devotional service because otherwise one will become victimized by the modes of material nature.
(Srimad Bhagavatam----6:4:14----purport).
As confirmed in Bhagavad-gītā: "One who engages in full devotional service, who does not fall down in any circumstance, at once transcends the modes of material nature and thus comes to the level of Brahman." One who fully engages in the devotional service of the Lord is immediately raised to the transcendental position, which is the brahma-bhūta stage.
(Srimad Bhagavatam----7:6:26----purport).
If one engages himself in the service of Kṛṣṇa or His plenary expansions with unfailing determination, although these modes of material nature are very difficult to overcome, one can overcome them easily. This has already been explained in the Seventh Chapter. One who surrenders unto Kṛṣṇa at once surmounts the influence of the modes of material nature.
(Bhagavad-Gita----14:26----purport).
Spiritual education changes one's consciousness so that one simply carries out the orders of the Supreme Lord and becomes free from the influence of the modes of material nature.
(Srimad Bhagavatam----7:2:41----purport).
A person in Kṛṣṇa consciousness is always transcendental to the material modes of nature. He has no expectations for the result of the work entrusted to him, because he is above false ego and pride. Still, he is always enthusiastic till the completion of such work. He does not worry about the distress undertaken; he is always enthusiastic. He does not care for success or failure; he is equal in both distress and happiness. Such a worker is situated in the mode of goodness.
(Bhagavad-Gita----18:26----purport).
Because the Lord is the property of the devotees, and the devotees are the property of the Lord reciprocally, the devotees are certainly transcendental to the modes of material nature.
(Srimad Bhagavatam----1:8:27----purport).
The living entities change their material bodies in different shapes and forms under the influence of the different modes of material nature, but in the transcendental state the devotee is guṇa-tīta, or above the material modes of goodness, passion and ignorance.
(Srimad Bhagavatam----2:2:17----purport).
Those who constantly engage in devotional service are situated in a transcendental state, above the material modes of nature.
(Srimad Bhagavatam----10:1:41----purport).
Devotees who awaken their transcendental nature in the presence of the Lord and who follow the rules and regulations of devotional service can understand Lord Kṛṣṇa, Lord Rāmacandra and other incarnations, who are not of this material world but who come from the spiritual world for the benefit of people in general.
(Srimad Bhagavatam----10:2:35----purport).
Becoming fully Kṛṣṇa conscious, one is freed from all dualities and thus is free from the contaminations of the material modes.
(Bhagavad-Gita----4:23----purport).
