A pure devotee of the Lord automatically develops all godly qualities, and some of the prominent features of those qualities are as follows: he is kind, peaceful, truthful, equable, faultless, magnanimous, mild, clean, nonpossessive, a well-wisher to all, satisfied, surrendered to Kṛṣṇa, without hankering, simple, fixed, self-controlled, a balanced eater, sane, mannerly, prideless, grave, sympathetic, friendly, poetic, expert and silent.
(Srimad Bhagavatam-----2:3:13-----purport).

"My dear Arjuna, you are very dear to Me, and therefore only for your good I will disclose the most secret part of My instructions. It is simply this: become a pure devotee of Mine and give yourself unto Me only, and I promise you full spiritual existence, by which you may gain the eternal right of transcendental loving service unto Me. Just give up all other ways of religiosity and exclusively surrender unto Me and believe that I will protect you from your sinful acts, and I shall deliver you. Do not worry any more."
(Srimad Bhagavatam-----2:4:16-----purport).

In the Caitanya-caritāmṛta, the devotee's desirable qualities are described to be twenty-six in number. They are stated as follows: He is very kind; he does not quarrel with anyone; he accepts Kṛṣṇa consciousness as the highest goal of life; he is equal to everyone; no one can find fault in his character; he is magnanimous, mild and always clean, internally and externally; he does not profess to possess anything in this material world; he is a benefactor to all living entities; he is peaceful and is a soul completely surrendered to Kṛṣṇa; he has no material desire to fulfill; he is meek and humble, always steady, and has conquered the sensual activities; he does not eat more than required to maintain body and soul together; he is never mad after material identity; he is respectful to all others and does not demand respect for himself; he is very grave, very compassionate and very friendly; he is poetic; he is expert in all activities, and he is silent in nonsense.
(Srimad Bhagavatam-----3:15:25-----purport).

Kṛṣṇa says, "Give up all other religious principles and simply become a soul surrendered unto Me." This is religion. When one is fully conscious that Kṛṣṇa is the supreme enjoyer and Supreme Lord and one acts accordingly, that is real religion.
(Srimad Bhagavatam-----3:15:33-----purport).

According to Bhagavad-gītā, Seventh Chapter, the laws of nature are so stringent that it is impossible for the living entity to surpass their enforcement. It is also explained that only those who are fully surrendered to Kṛṣṇa in Kṛṣṇa consciousness can be saved. We can learn from the description of the Śrīmad-Bhāgavatam that it is because of the birth of two great demons that there were so many natural disturbances.
(Srimad Bhagavatam-----3:17:15-----purport).

A devotee, therefore, is always conscious of his real position. Only by his full surrender to the Lord, by the Lord's grace, are his sufferings made shorter. As stated in Bhagavad-gītā, "Surrender unto Me, and I will give you protection from all kinds of sinful reaction." That is His mercy. But this does not mean that one who has surrendered to the lotus feet of the Lord has committed no misdeeds in his past life. A devotee always prays, "For my misdeeds, may I be born again and again, but my only prayer is that I may not forget Your service."
(Srimad Bhagavatam-----3:25:39-40-----purport).

It is stated in Bhagavad-gītā that the spell of māyā, which covers the knowledge of the living entity, is insurmountable. However, one who surrenders unto Kṛṣṇa, the Supreme Personality of Godhead, can conquer this seemingly insurmountable spell of māyā. Here also it is stated that the daivī prakṛti, or the external energy of the Supreme Lord, is durvibhāvyā, very difficult to understand and very difficult to conquer.
(Srimad Bhagavatam-----3:28:44-----purport).

Lord Kṛṣṇa is personally canvassing, "Give up everything in this material world. Come to Me, and I shall give you all protection," but we are not agreeable. We think, "We are quite all right. Why should we surrender unto Kṛṣṇa and go back to His kingdom?" This is called illusion, or māyā. Everyone is satisfied with his standard of living, however abominable it may be.
(Srimad Bhagavatam-----3:30:5-----purport).

As the Supreme Lord puts the living entity into the condition of horrible existence, He can also deliver him, and therefore one should seek shelter at the lotus feet of Kṛṣṇa. Kṛṣṇa demands, "Give up everything and surrender unto Me." And it is also said in Bhagavad-gītā that anyone who approaches Him does not come back again to accept a form in material existence, but goes back to Godhead, back home, never to return.
(Srimad Bhagavatam-----3:31:12-----purport).

Māyā is so strong that the Lord says that it is very difficult to surmount her influence. But one can do so very easily "if he surrenders unto Me." Mām eva ye prapadyante: anyone who surrenders unto Him can overcome the influence of the stringent laws of material nature. It is clearly said here that a living entity is put under the influence of māyā by His will, and if anyone wants to get out of this entanglement, this can be made possible simply by His mercy.
(Srimad Bhagavatam-----3:31:15-----purport).

When a conditioned soul is seriously anxious to get out of the influence of the material clutches, the Supreme Personality of Godhead, who is situated within him as Paramātmā, gives him this knowledge: "Surrender unto Me." As the Lord says in Bhagavad-gītā, "Give up all other engagements. Just surrender unto Me." It is to be accepted that the source of knowledge is the Supreme Person.
(Srimad Bhagavatam-----3:31:16-----purport).

As it is confirmed in Bhagavad-gītā, only one who surrenders unto Kṛṣṇa, the Supreme Personality of Godhead, can be liberated from the clutches of māyā. Brahmā is called here ādyaḥ sthira-carāṇām. He is the original, first-created living entity, and after his own birth he creates the entire cosmic manifestation.
(Srimad Bhagavatam-----3:32:12-15-----purport).

When Kṛṣṇa says, man-manā bhava mad-bhaktaḥ (B.G.18:65)—"Always think of Me, become My devotee, and surrender unto Me"—the so-called scholars comment that it is not to Kṛṣṇa that we have to surrender. That is envy.

The Lord states in Bhagavad-gītā (7.14):
daivī hy eṣā guṇa-mayī
mama māyā duratyayā
mām eva ye prapadyante
māyām etāṁ taranti te
"My divine energy consisting of the three modes of material nature is difficult to overcome. But those who have surrendered unto Me can easily cross beyond it." A Vaiṣṇava should take care of those who are bewildered by this māyā instead of becoming angry with them, because without a Vaiṣṇava's mercy they have no way to get out of the clutches of māyā. Those who have been condemned by māyā are rescued by the mercy of devotees.
(Srimad Bhagavatam-----4:6:49-----purport).

In Bhagavad-gītā Lord Kṛṣṇa says, "Simply surrender unto Me, and I will give you protection from all the reactions of sinful activities." This material world is so created that one has to act sinfully, knowingly or unknowingly, and unless his life is dedicated to Viṣṇu, he has to suffer all the reactions of sinful activities.
(Srimad Bhagavatam-----4:7:42-----purport).

The independence of the conditioned soul does not mean to fight with the obstacles offered by māyā, but to surrender to Kṛṣṇa. In the material world, everyone is trying to become completely independent simply by fighting against the obstacles offered by māyā. This is called the struggle for existence.
(Srimad Bhagavatam-----4:9:35-----purport).

The supreme īśvara puruṣottama is Lord Kṛṣṇa. He exhibits His powers as īśvara, or the supreme controller, when He assures His devotee in Bhagavad-gītā (18.66): "Abandon all varieties of religion and just surrender unto Me. I shall deliver you from all sinful reaction. Do not fear." He can immediately make His devotee immune from all the reactions caused by sinful life if the devotee simply surrenders unto Him.
(Srimad Bhagavatam-----4:19:3-----purport).

As stated in Bhagavad-gītā (7.19):
bahūnāṁ janmanām ante
jñānavān māṁ prapadyate
vāsudevaḥ sarvam iti
sa mahātmā sudurlabhaḥ
"After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare."
Lord Śiva is rarely seen by common men, and similarly a person who is fully surrendered unto Vāsudeva, Kṛṣṇa, is also very rarely seen because a person who is fully surrendered unto the Supreme Lord is very rare (sa mahātmā sudurlabhaḥ).
(Srimad Bhagavatam-----4:24:28-----purport).

Since Vāsudeva is the ultimate truth, Lord Śiva openly proclaims that one who is a devotee of Lord Vāsudeva, who is surrendered to Lord Kṛṣṇa, is actually very dear to him. Lord Vāsudeva, Kṛṣṇa, is worshipable not only by ordinary living entities but by demigods like Lord Śiva, Lord Brahmā and others.
(Srimad Bhagavatam-----4:24:28-----purport).

A person who executes his occupational duty properly for one hundred births becomes qualified to occupy the post of Brahmā, and if he becomes more qualified, he can approach Lord Śiva. A person who is directly surrendered to Lord Kṛṣṇa, or Viṣṇu, in unalloyed devotional service is immediately promoted to the spiritual planets. Lord Śiva and other demigods attain these planets after the destruction of this material world.
(Srimad Bhagavatam-----4:24:29-----translation).

Jīva kṛṣṇa-dāsa, ei viśvāsa, karle ta' āra duḥkha nāi: "Please therefore accept yourself as the servant of Kṛṣṇa. Then you will be freed from all miseries." As soon as one surrenders to Kṛṣṇa and accepts the perfect standard of knowledge, which is Bhagavad-gītā as it is, he then comes out of the material modes of nature and does not fall down and lose his knowledge.
(Srimad Bhagavatam-----4:26:8-----purport).

The actual reality is Kṛṣṇa and service to Kṛṣṇa, which can save us from the clutches of māyā, for the Lord says in Bhagavad-gītā (7.14), mām eva ye prapadyante māyām etāṁ taranti te: "Those who surrender unto Me can easily cross beyond My illusory energy."
(Srimad Bhagavatam-----4:29:2b-----purport).

A liberated soul is a person who has sufficient knowledge of this material world and is therefore unattached to the bodily conception of life. But because of association with the modes of material nature for a very long time, even liberated souls sometimes become captivated by the illusory energy due to inattentiveness in the transcendental position. Therefore Lord Kṛṣṇa says in Bhagavad-gītā (7.14), mām eva ye prapadyante māyām etāṁ taranti te: "Only those who surrender unto Me can overcome the influence of the material energy." Therefore no one should think of himself as a liberated person immune to the influence of māyā. Everyone should very cautiously execute devotional service by rigidly following regulative principles. Thus he will remain fixed at the lotus feet of the Lord. Otherwise, a little inattention will create havoc.
(Srimad Bhagavatam-----5:18:4-----purport).

One who has taken birth in the land of Bhārata-varṣa has a full opportunity to study the direct instructions given by Kṛṣṇa in Bhagavad-gītā and thus finally decide what to do in his human form of life. One should certainly give up all other propositions and surrender to Kṛṣṇa.
(Srimad Bhagavatam-----5:19:23-----purport).

Śrīla Viśvanātha Cakravartī Ṭhākura mentions that although Mahārāja Parīkṣit was a pure devotee, Śukadeva Gosvāmī did not immediately speak to him about the strength of devotional service. As stated in Bhagavad-gītā (14.26):
māṁ ca yo 'vyabhicāreṇa
bhakti-yogena sevate
sa guṇān samatītyaitān
brahma-bhūyāya kalpate
Devotional service is so strong that if one fully surrenders to Kṛṣṇa and takes fully to His devotional service, the reactions of his sinful life immediately stop.
(Srimad Bhagavatam-----6:1:7-----purport).

Parīkṣit Mahārāja had inquired from Śukadeva Gosvāmī how one can be saved from falling into the various conditions of hellish life. In this verse Śukadeva Gosvāmī answers that a soul who has surrendered to Kṛṣṇa certainly cannot go to naraka, hellish existence. To say nothing of going there, even in his dreams he does not see Yamarāja or his order carriers, who are able to take one there. In other words, if one wants to save himself from falling into naraka, hellish life, he should fully surrender to Kṛṣṇa. The word sakṛt is significant because it indicates that if one sincerely surrenders to Kṛṣṇa once, he is saved even if by chance he falls down by committing sinful activities.
(Srimad Bhagavatam-----6:1:19-----purport).

The sinful actions of one who has surrendered unto Kṛṣṇa are compared to a snake with its poison fangs removed (protkhāta-daṁṣṭrāyate). Such a snake is no longer to be feared. Of course, one should not commit sinful activities on the strength of having surrendered to Kṛṣṇa. However, even if one who has surrendered to Kṛṣṇa happens to do something sinful because of his former habits, such sinful actions no longer have a destructive effect.
(Srimad Bhagavatam-----6:1:19-----purport).

Because neophyte devotees cannot understand what the forms of Nārāyaṇa, Vāsudeva and Govinda are, Kṛṣṇa directly says, mām ekam. Herein, this is also supported by the word kṛṣṇa-padāravindayoḥ. Nārāyaṇa does not speak personally, but Kṛṣṇa, or Vāsudeva, does, as in Bhagavad-gītā for example. Therefore, to follow the direction of Bhagavad-gītā means to surrender unto Kṛṣṇa, and to surrender in this way is the highest perfection of bhakti-yoga.
(Srimad Bhagavatam-----6:1:19-----purport).

We first advise all the disciples in our Kṛṣṇa consciousness movement to avoid illicit sex, which is the beginning of all abominable life and which is followed by meat-eating, gambling and intoxication, one after another. Of course, restraint is very difficult, but it is quite possible if one fully surrenders to Kṛṣṇa, since all these abominable habits gradually become distasteful for a Kṛṣṇa conscious person.
(Srimad Bhagavatam-----6:1:22-----purport).

The more society allows prostitution and illicit sex, the more impetus it gives to cheaters, thieves, plunderers, drunkards and gamblers. Therefore we first advise all the disciples in our Kṛṣṇa consciousness movement to avoid illicit sex, which is the beginning of all abominable life and which is followed by meat-eating, gambling and intoxication, one after another. Of course, restraint is very difficult, but it is quite possible if one fully surrenders to Kṛṣṇa, since all these abominable habits gradually become distasteful for a Kṛṣṇa conscious person. If illicit sex is allowed to increase in a society, however, the entire society will be condemned, for it will be full of rogues, thieves, cheaters and so forth.
(Srimad Bhagavatam-----6:1:22-----purport).

"The living entities in this conditioned world are My eternal, fragmental parts. Due to conditioned life, they are struggling very hard with the six senses, which include the mind." The living entity's struggle for existence within the material world is due to his rebellious nature. Unless a living entity surrenders to Kṛṣṇa, he must continue this life of struggle.
(Srimad Bhagavatam-----6:4:44-----purport).

When one falls in the river of nescience, he is always tossed here and there by the waves, but the same māyā can also save him when be surrenders to Kṛṣṇa, or becomes Kṛṣṇa conscious. Kṛṣṇa consciousness is knowledge and austerity. A Kṛṣṇa conscious person takes knowledge from the Vedic literature, and at the same time he must practice austerities.
(Srimad Bhagavatam-----6:5:16-----purport).

Everyone is indebted to the demigods, to living entities in general, to his family, to the pitās and so on, but if one fully surrenders to Kṛṣṇa, Mukunda, who can give one liberation, even if one performs no yajñas, one is freed from all debts.
(Srimad Bhagavatam-----6:5:37-----purport).

Kṛṣṇa wants everyone to surrender unto Him because everyone is constitutionally His servant. Therefore, as a sincere friend of Kṛṣṇa, one should preach this philosophy, requesting everyone to surrender unto Kṛṣṇa. Ātma-nivedanam means offering Kṛṣṇa everything, including one's body, mind, intelligence and whatever one may possess.
(Srimad Bhagavatam-----7:5:23-24-----purport).

Prahlāda Mahārāja has also explained that a child's protectors, his parents, cannot save the child from the onslaught of birth and death, nor can medicine and a physician save one from death, nor can a boat or similar means of protection save a person drowning in the water, for everything is controlled by the Supreme Personality of Godhead. Therefore suffering humanity must surrender to Kṛṣṇa, as Kṛṣṇa Himself demands in the last instruction of Bhagavad-gītā.
(Srimad Bhagavatam-----7:9:22-----purport).
