"Pure devotees are so absorbed in thought of Krishna that they have no other engagement; although they may seem to think or act otherwise, they are always thinking of Krishna. The smile of such a Krishna conscious person is so attractive that simply by smiling he wins so many admirers, disciples and followers."
(Srimad-Bhagavatam 3.22.21, Purport)
"The sun is far above the planetary systems, and there is no possibility of its being covered by any kind of cloud; similarly, when a devotee is purified like the sun, from his pure heart there is a diffusion of ecstatic love which is more glorious than the sunshine."
(Nectar of Devotion, Chapter 17)
"When a diamond is set in a golden ring, it looks very nice. The gold is glorified, and at the same time the diamond is glorified. The Lord and the living entity eternally glitter, and when a living entity becomes inclined to the service of the Supreme Lord he looks like gold. The Lord is a diamond, and so this combination is very nice. Living entities in a pure state are called devotees. The Supreme Lord becomes the devotee of His devotees."
(Bhagavad-gita As It Is 9.29, Purport)
"A pure devotee cannot forget the Supreme Lord for a moment, and similarly, the Supreme Lord cannot forget His pure devotee for a moment."
(Bhagavad-gita As It Is 8.15, Purport)
"For the pure devotee of the Lord there is nothing beyond the lotus feet of the Lord, and the Lord knows that such devotees do not wish anything more than that. The Lord also does not wish to be separated from the lotus hearts of those pure devotees."
(Srimad-Bhagavatam 3.9.5, Purport)
"A pure devotee of the Lord does not live on any planet of the material sky, nor does he feel any contact with material elements. His so-called material body does not exist, being surcharged with the spiritual current of the Lord's identical interest, and thus he is permanently freed from all contaminations of the sum total of the mahat-tattva. He is always in the spiritual sky, which he attains by being transcendental to the sevenfold material covering by the effect of his devotional service. The conditioned souls are within the coverings, whereas the liberated soul is far beyond the cover."
(Srimad-Bhagavatam 1.13.55, Purport)
"Pure devotees of the Lord are more powerful than the waters of the sacred river Ganges. One can derive spiritual benefit out of prolonged use of the Ganges waters. But one can be sanctified at once by the mercy of a pure devotee of the Lord."
(Srimad-Bhagavatam 1.1.15, Purport)
"Srila Vrndavana dasa Thakura has sung that the devotees of Lord Caitanya are so powerful that each one of them can deliver a universe."
(Srimad-Bhagavatam 4.24.58, Purport)
"A man bound by the hands and feet cannot free himself -- he must be helped by a person who is unbound. Because the bound cannot help the bound, the rescuer must be liberated. Therefore, only Lord Krishna, or His bona fide representative the spiritual master, can release the conditioned soul."
(Bhagavad-gita As It Is 7.14, Purport)
"This material world is sometimes regarded as an ocean of nescience and sometimes as a blazing forest. In the ocean, however expert a swimmer one may be, the struggle for existence is very severe. If someone comes forward and lifts the struggling swimmer from the ocean, he is the greatest savior."
(Bhagavad-gita As It Is 4.36, Purport)
"Any man who has genuine devotion to the Lord has all the good qualities which are found in godly persons or in the demigods, whereas the nondevotee, however advanced he may be in material qualifications by education and culture, lacks in godly qualities."
(Bhagavad-gita As It Is 1.28, Purport)
"The most important characteristic of a pure devotee is that he is not lampata, or licentious, and another quality is that he is always eager to mitigate the miseries of suffering humanity. The most obnoxious misery of a living entity is his forgetfulness of Krishna. A pure devotee, therefore, always tries to evoke everyone's Krishna consciousness. This is the panacea for all miseries."
(Srimad-Bhagavatam 3.14.49, Purport)
"As fog is vanquished at the first glimpse of sunlight, one's sinful reactions are automatically vanquished as soon as one begins serving a pure devotee; no separate endeavor is required."
(Srimad-Bhagavatam 6.1.16, Purport)

"O son of Prtha, those who are not deluded, the great souls, are under the protection of the divine nature. They are fully engaged in devotional service because they know Me as the Supreme Personality of Godhead, original and inexhaustible. Always chanting My glories, endeavoring with great determination, bowing down before Me, these great souls perpetually worship Me with devotion."
(Bhagavad-gita As It Is 9.13-14)
"A pure devotee accepts the transcendental loving service of the Lord but rejects all kinds of liberation for his personal sense gratification. This is stated by Lord Kapila in Srimad-Bhagavatam (3.29.11-14), in His explanation of the nature of pure devotional service. As soon as a pure devotee hears the glories and transcendental qualities of the Supreme Personality of Godhead, who is seated in everyone’s heart, his mind at once flows toward the Lord, just as the waters of the Ganges flow down toward the sea. Such spontaneous attraction of the devotee’s mind to the service of the Supreme Personality of Godhead signifies pure devotional service."
(Teachings of Lord Caitanya, Ch. 1)
"All the pure devotees are as bright as sunshine, and their bodily luster is very effulgent. In addition, their performance of sankirtana is unparalleled. There are many professional chanters who can perform congregational chanting with various musical instruments in an artistic and musical way, but their chanting cannot be as attractive as the congregational chanting of pure devotees."
(Caitanya-caritamrta Madhya 11.95, Purport)
"One who is situated in devotional service is certainly the controller of his senses, and thus he is a liberated person. When such a liberated person, the pure devotee, hears of the transcendental qualities and activities of the Lord's incarnations for the performance of various pastimes, his hair stands on end on his body, tears fall from his eyes, and in his spiritual realization his voice falters. Sometimes he very openly dances, sometimes he sings loudly, and sometimes he cries. Thus he expresses his transcendental jubilation."
"For a pure devotee, there is no scope for indulgence in mystic yoga practice or the cultivation of speculative philosophy. It is indeed impossible for a pure devotee to engage his mind in such unwanted activities. Even if a pure devotee wanted to, his mind would not allow him to do so. That is a characteristic of a pure devotee -- he is transcendental to all fruitive activity, speculative philosophy and mystic yoga meditation."
(Caitanya-caritamrta Madhya 13.14,, Purport)
"The pure devotee has no actual chance to fall down because the Supreme Godhead personally takes care of His pure devotees."
(Bhagavad-gita As It Is 9.34, Purport)
"The pure devotee is actually equal to everyone, as confirmed in Bhagavad-gita (18.54): brahma-bhutah prasannatma na socati na kanksati/ samah sarvesu bhutesu. Universal brotherhood is possible when one is a pure devotee (panditah sama-darsinah)."
(Srimad-Bhagavatam 9.4.66, Purport)
"The uttama-adhikari, or the highest devotee, is one who is very advanced in devotional service. An uttama-adhikari is not interested in blaspheming others, his heart is completely clean, and he has attained the realized state of unalloyed Krishna consciousness. According to Srila Rupa Gosvami, the association and service of such a maha-bhagavata, or perfect Vaisnava, are most desirable."
(Nectar of Instruction Text 5, Purport)
"A pure devotee is neither happy nor distressed over material gain and loss, nor is he very much anxious to get a son or disciple, nor is he distressed by not getting them. If he loses anything which is very dear to him, he does not lament. Similarly, if he does not get what he desires, he is not distressed. He is transcendental in the face of all kinds of auspicious, inauspicious and sinful activities. He is prepared to accept all kinds of risks for the satisfaction of the Supreme Lord. Nothing is an impediment in the discharge of his devotional service. Such a devotee is very dear to Krishna."
(Bhagavad-gita As It Is 12.17, Purport)
"Srila Bilvamangala Thakura realized that if one develops his natural devotional service to the Supreme Personality of Godhead, mukti stands before him with folded hands to offer all kinds of service. In other words, the devotee is already liberated. There is no need for him to aspire for different types of liberation. The pure devotee automatically achieves liberation, even without desiring it."
(Srimad-Bhagavatam 9.4.67, Purport)
"The spiritual master is addressed as 'Prabhupada' because he is a completely self-realized soul. The word pada means 'position' and Prabhupada indicates that he is given the position of prabhu, or the Supreme Personality of Godhead, for he acts on behalf of the Supreme Personality of Godhead."
(Srimad-Bhagavatam 4.23.18, Purport)
"The verdict of all revealed scriptures is that by even a moment's association with a pure devotee, one can attain all success."
(Caitanya-caritamrta Madhya 22.54)
"Even the most learned or experienced person cannot understand the movements of a Vaisnava, a pure devotee. No one, therefore, should criticize a pure Vaisnava. A Vaisnava knows his own business; whatever he does is precisely right because he is always guided by the Supreme Personality of Godhead."
(Srimad-Bhagavatam 9.4.68, Purport)
