In his Bṛhad-bhāgavatāmṛta, Śrīla Sanātana Gosvāmī has explained that the attainment of salvation by merging into the Brahman effulgence of the Lord cannot be accepted as the highest success in life, because demons like Kaṁsa, who were famous for killing brāhmaṇas and cows, attained that salvation. For devotees such salvation is abominable. Devotees are actually in a transcendental position, whereas nondevotees are candidates for hellish conditions of life. There is always a difference between the life of a devotee and the life of a demon, and their realizations are as different as heaven and hell.
(Sri Caitanya Caritamrta------1:5:36------purport).

Everyone depends upon dharma (religiosity), artha (economic development), kāma (sense gratification) and ultimately mokṣa (salvation), but Śrī Caitanya Mahāprabhu, due to His magnanimous character, can give more than salvation. Therefore in this verse the words hīnārthādhika-sādhakam indicate that although by material estimationsalvation is of a quality superior to the inferior interests of religiosity, economic development and sense gratification, above salvation there is the position of devotional service and transcendental love for the Supreme Personality of Godhead. Śrī Caitanya Mahāprabhu is the bestower of this great benediction. Śrī Caitanya Mahāprabhu said, premā pum-artho mahān: "Love of Godhead is the ultimate benediction for all human beings." Śrīla Kṛṣṇadāsa Kavirāja Gosvāmī, the author of Śrī Caitanya-caritāmṛta, therefore first offers his respectful obeisances unto Lord Caitanya Mahāprabhu before describing His magnanimity in bestowing love of Godhead.
(Sri Caitanya Caritamrta------1:7:1------purport).

If someone becomes attached to the principles of salvation or to merging into the existence of the brahma-jyotir, his ecstasies gradually diminish into shadow and parā attachment or else transform into the principles of ahaṅgrahopāsanā. This ahaṅgrahopāsanā describes a living entity when he begins spiritual realization by identifying himself with the Supreme Lord. This state of self-realization is technically known as monism. The monist thinks himself one with the Supreme Lord. Thus, because he does not differentiate between himself and the Supreme Lord, it is his view that by worshiping himself he is worshiping the supreme whole.
(Nectar of Devotion).

Kṛṣṇa also possesses five other qualities, which are manifest in the body of Nārāyaṇa, and they are listed as follows. (56) He has inconceivable potency. (57) Uncountable universes generate from His body. (58) He is the original source of all incarnations. (59) He is the giver of salvation to the enemies whom He kills. (60) He is the attractor of liberated souls. All these transcendental qualities are manifest wonderfully in the personal feature of Lord Kṛṣṇa.
(Nectar of Devotion).

Following in the holy footsteps of Śrīla Śukadeva Gosvāmī, we have tried to present this book, Kṛṣṇa, for being read and heard by the conditioned souls of this age. By hearing the pastimes of Lord Kṛṣṇa, one is sure and certain to get salvation and be transferred back home, back to Godhead. It is stated by Śukadeva Gosvāmī that as we hear the transcendental pastimes of the Lord, we gradually cut the knots of material contamination. Therefore, regardless of what one is, if one wants the association of Lord Kṛṣṇa in the transcendental kingdom of God for eternity in blissful existence, one must hear about the pastimes of Lord Kṛṣṇa and chant the mahā-mantra, Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare / Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare.
(Krsna Book).

Of the saintly persons who are constantly engaged in striving toward salvation, one who is in Kṛṣṇa consciousness is the best of all. The Bhāgavatam (4.22.39) confirms this fact as follows:
yat-pāda-paṅkaja-palāśa-vilāsa-bhaktyā
karmāśayaṁ grathitam udgrathayanti santaḥ
tadvan na rikta-matayo yatayo 'pi ruddha-
sroto-gaṇās tam araṇaṁ bhaja vāsudevam
"Just try to worship, in devotional service, Vāsudeva, the Supreme Personality of Godhead. Even great sages are not able to control the forces of the senses as effectively as those who are engaged in transcendental bliss by serving the lotus feet of the Lord, uprooting the deep-grown desire for fruitive activities."

(Bhagavad-Gita------5:26------purport).

One should think of Kṛṣṇa and act for Kṛṣṇa favorably, not unfavorably. Kaṁsa was an enemy of Kṛṣṇa's. From the very beginning of Kṛṣṇa's birth, Kaṁsa planned in so many ways to kill Him, and because he was always unsuccessful, he was always thinking of Kṛṣṇa. Thus while working, while eating and while sleeping, he was always Kṛṣṇa conscious in every respect, but that Kṛṣṇa consciousness was not favorable, and therefore in spite of his always thinking of Kṛṣṇa twenty-four hours a day, he was considered a demon, and Kṛṣṇa at last killed him. Of course anyone who is killed by Kṛṣṇa attains salvation immediately, but that is not the aim of the pure devotee. The pure devotee does not even want salvation. He does not want to be transferred even to the highest planet, Goloka Vṛndāvana. His only objective is to serve Kṛṣṇa wherever he may be.

(Bhagavad-Gita------11:55------purport).

Real religion means to know God, our relation with Him and our duties in relation with Him and to know ultimately our destination after leaving this material body. The conditioned souls, who are entrapped by the material energy, hardly know all these principles of life. Most of them are like animals engaged in eating, sleeping, fearing and mating. They are mostly engaged in sense enjoyment under the pretension of religiosity, knowledge or salvation. They are still more blind in the present age of quarrel, or Kali-yuga. In the Kali-yuga the population is just a royal edition of the animals. They have nothing to do with spiritual knowledge or godly religious life. They are so blind that they cannot see anything beyond the needs of the body. They have no information of the spirit soul beyond the jurisdiction of the subtle mind, intelligence or ego, but they are very much proud of their advancement in knowledge, science and material prosperity.

(Srimad Bhagavatam------1:3:43------purport).

As far as salvation is concerned, one has to conquer the principles of lust, anger, unlawful desires, avarice and bewilderment. To get freedom from anger, one should learn how to forgive. To be free from unlawful desires one should not make plans. By spiritual culture one is able to conquer sleep. By tolerance only can one conquer desires and avarice. Disturbances from various diseases can be avoided by regulated diets. By self-control one can be free from false hopes, and money can be saved by avoiding undesirable association. By practice of yoga one can control hunger, and worldliness can be avoided by culturing the knowledge of impermanence. Dizziness can be conquered by rising up, and false arguments can be conquered by factual ascertainment. Talkativeness can be avoided by gravity and silence, and by prowess one can avoid fearfulness. Perfect knowledge can be obtained by self-cultivation. One must be free from lust, avarice, anger, dreaming, etc., to actually attain the path of salvation.
