One devotee may want Kṛṣṇa as supreme master, another as his personal friend, another as his son, and still another as his lover. Kṛṣṇa rewards all the devotees equally, according to their different intensities of love for Him. In the material world, the same reciprocations of feelings are there, and they are equally exchanged by the Lord with the different types of worshipers. The pure devotees both here and in the transcendental abode associate with Him in person and are able to renderpersonal service to the Lord and thus derive transcendental bliss in His loving service. As for those who are impersonalists and who want to commit spiritual suicide by annihilating the individual existence of the living entity, Kṛṣṇa helps also by absorbing them into His effulgence. Such impersonalists do not agree to accept the eternal, blissful Personality of Godhead; consequently they cannot relish the bliss of transcendental personal service to the Lord, having extinguished their individuality. Some of them, who are not firmly situated even in the impersonal existence, return to this material field to exhibit their dormant desires for activities.
(Bhagavad Gita----4:11----purport).

The question of who is better—one who is engaged in the path of impersonal Brahman or one who is engaged in the personal service of the Supreme Personality of Godhead—was raised by Arjuna, and the Lord replied to him so explicitly that there is no doubt that devotional service to the Personality of Godhead is the best of all processes of spiritual realization.
(Bhagavad Gita----12:20----purport).

From the personal example of Śrī Nārada Muni in his previous birth, it is clear that the service of the Lord begins with the service of the Lord's bona fide servants. The Lord says that the service of His servants is greater than His personal service. Service of the devotee is more valuable than the service of the Lord. One should therefore choose a bona fide servant of the Lord constantly engaged in His service, accept such a servant as the spiritual master and engage himself in his (the spiritual master's) service. Such a spiritual master is the transparent medium by which to visualize the Lord, who is beyond the conception of the material senses. By service of the bona fide spiritual master, the Lord consents to reveal Himself in proportion to the service rendered.
(Srimad Bhagavatam-----1:5:23----purport).

In Bhagavad-gītā (12.5) it is said that the impersonalist undergoes a series of difficult programs on account of his impersonal meditation. But the devotee, due to the Lord's personal service, progresses very easily. Impersonal meditation is therefore a source of suffering for the impersonalist. Here, the devotee has an advantage over the impersonalist philosopher. The impersonalist is doubtful about the personal feature of the Lord, and therefore he always tries to meditate upon something which is not objective. For this reason there is an authentic statement in the Bhāgavatam regarding the positive concentration of the mind on the factual form of the Lord.
(Srimad Bhagavatam-----2:2:12----purport).

When one engages in devotional service to the Lord in the nine different kinds of bhakti-yoga, as enunciated in authoritative scriptures, such as hearing (śravaṇam), chanting (kīrtanam), remembering, offering worship, praying and offering personal service—either in one of them, or two or three or all of them—he naturally has no opportunity to engage in the service of the three modes of material nature.
(Srimad Bhagavatam-----3:25:27----purport).

A devotee becomes accustomed to serving the Supreme Lord by purification of his senses. In other words, the yoga principles of meditation are required as long as one is not situated in pure devotional service. The mind is used to purify the senses, but when the senses are purified by meditation, there is no need to sit in a particular place and try to meditate upon the form of the Lord. One becomes so habituated that he automatically engages in the personal service of the Lord. When the mind forcibly is engaged upon the form of the Lord, this is called nirbīja-yoga, or lifeless yoga, for the yogī does not automatically engage in the personal service of the Lord. But when he is constantly thinking of the Lord, that is called sabīja-yoga, or living yoga. One has to be promoted to the platform of living yoga.
(Srimad Bhagavatam-----3:28:34----purport).

The child prays that it is better to remain within the womb of darkness and be constantly absorbed in Kṛṣṇa consciousness than to get out and again fall a victim to the illusory energy. The illusory energy acts within the abdomen as well as outside the abdomen, but the trick is that one should remain Kṛṣṇa conscious, and then the effect of such a horrible condition cannot act unfavorably upon him. In Bhagavad-gītā it is said that one's intelligence is his friend, and the same intelligence can also be his enemy. Here also the same idea is repeated: suhṛdātmanaiva, friendly intelligence. Absorption of intelligence in the personal service of Kṛṣṇa and full consciousness of Kṛṣṇa always are the path of self-realization and liberation. Without being unnecessarily agitated, if we take to the process of Kṛṣṇa consciousness by constantly chanting Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, the cycle of birth and death can be stopped for good.
(Srimad Bhagavatam-----3:31:21----purport).
