If the illusory energy subsides and the living entity becomes fully enriched with knowledge by the grace of the Lord, then he becomes at once enlightened with self-realization and thus becomes situated in his own glory.
(Srimad Bhagavatam---1:3:34---translation).

Confidential devotees of the Lord see in every step a benedictory direction of the Lord. What is considered to be an odd or difficult moment in the mundane sense is accepted as special mercy of the Lord. Mundane prosperity is a kind of material fever, and by the grace of the Lord the temperature of this material fever is gradually diminished, and spiritual health is obtained step by step. Mundane people misunderstand it.
(Srimad Bhagavatam---1:6:10---purport).

As long as the sunshine is there, our eyes are useful to a certain extent. But in the absence of sunshine, the eyes are useless. Lord Śrī Kṛṣṇa, being the primeval Lord, the Supreme Truth, is compared to the sun. Without Him all our knowledge is either false or partial. The opposite of the sun is the darkness, and similarly the opposite of Kṛṣṇa is māyā, or illusion. The devotees of the Lord can see everything in true perspective due to the light disseminated by Lord Kṛṣṇa. By the grace of the Lord the pure devotee cannot be in the darkness of ignorance. Therefore, it is necessary that we must always be in the sight of Lord Kṛṣṇa so that we can see both ourselves and the Lord with His different energies. As we cannot see anything in the absence of the sun, so also we cannot see anything including our own self, without the factual presence of the Lord. Without Him all our knowledge is covered by illusion.
(Srimad Bhagavatam---1:11:9---purport).

Thus the function of the pure soul is revived in spiritual realization. This practical realization of the living being is made possible due to his becoming free from the reaction of the three modes of material nature, namely goodness, passion and ignorance. By the grace of the Lord, a pure devotee is at once raised to the place of the Absolute, and there is no chance of the devotee's becoming materially entangled again in conditioned life. One is not able to feel the presence of the Lord in all circumstances until one is endowed with the required transcendental vision made possible by devotional service prescribed in the revealed scriptures.
(Srimad Bhagavatam---1:15:31---purport).

Whatever plan the Supreme Personality of Godhead contemplates immediately fructifies. Similarly, a devotee who is completely dependent on the Supreme Lord can also fulfill his wishes by the grace of the Lord. The Lord fulfills His wishes independently, but a devotee fulfills his wishes simply by being dependent on the Supreme Personality of Godhead.
(Srimad Bhagavatam---4:12:32---purport).

A devotee is inspired by the Supersoul within the heart to advance in devotional service in a variety of ways. The devotee does not feel hackneyed or stereotyped, nor does he feel that he is in a stagnant position. In the material world, if one engages in chanting a material name, he will feel tired after chanting a few times. However, one can chant the Hare Kṛṣṇa mahā-mantra all day and night and never feel tired. As chanting is increased, it will come out new and fresh. Śrīla Rūpa Gosvāmī said that if he could somehow get millions of ears and tongues, then he could relish spiritual bliss by chanting the Hare Kṛṣṇa mahā-mantra. There is really nothing uninspiring for a highly advanced devotee. In Bhagavad-gītā the Lord says that He is situated in everyone's heart and that He helps the living entity forget and remember. By the grace of the Lord, the devotee gets inspiration.
(Srimad Bhagavatam---4:30:20---purport).

If by the Lord's grace one can understand Him, one will immediately be delivered, even within his material body. The material body will no longer have any function, and whatever activities take place with the body will be activities of Kṛṣṇa consciousness. In this way one may give up his body and return home, back to Godhead.
(Srimad Bhagavatam----8:3:6---purport).
