"One should render transcendental loving service to the Supreme Lord Kṛṣṇa favorably and without desire for material profit or gain through fruitive activities or philosophical speculation. That is called pure devotional service." (Bhakti-rasāmṛta-sindhu 1.1.11)
(Srimad Bhagavatam-----7:13:24-----purport).

The mission of Kṛṣṇa is to spread Kṛṣṇa consciousness all over the world, and for this purpose we naturally must have sufficient money. Therefore, according to the advice of Śrīla Rūpa Gosvāmī Prabhupāda, we should not give up attachment to money that can spread the Kṛṣṇa consciousness movement. Śrīla Rūpa Gosvāmī says in his Bhakti-rasāmṛta-sindhu (1.2.256):
prāpañcikatayā buddhyā
hari-sambandhi-vastunaḥ
mumukṣubhiḥ parityāgo
vairāgyaṁ phalgu kathyate
"When persons eager to achieve liberation renounce things which are related to the Supreme Personality of Godhead, though they are material, this is called incomplete renunciation." Money that can help in spreading the Kṛṣṇa consciousness movement is not a part of the material world, and we should not give it up, thinking that it is material.

(Srimad Bhagavatam-----7:13:32-----purport).

"When one is not attached to anything, but at the same time accepts everything in relation to Kṛṣṇa, one is rightly situated above possessiveness." (Bhakti-rasāmṛta-sindhu 1.2.255) Money is undoubtedly coming in great quantities, but we should not be attached to this money for sense gratification; every cent should be spent for spreading the Kṛṣṇa consciousness movement, not for sense gratification. There is danger for a preacher when he receives great quantities of money, for as soon as he spends even a single cent of the collection for his personal sense gratification, he becomes a fallen victim. The preachers of the Kṛṣṇa consciousness movement should be extremely careful not to misuse the immense quantities of money needed to spread this movement. Let us not make this money the cause of our distress; it should be used for Kṛṣṇa, and that will cause our eternal happiness. Money is Lakṣmī, or the goddess of fortune, the companion of Nārāyaṇa. Lakṣmījī must always remain with Nārāyaṇa, and then there need be no fear of degradation.
(Srimad Bhagavatam-----7:13:32-----purport).

"One who rejects anything without knowledge of its relationship to Kṛṣṇa is incomplete in his renunciation." (Bhakti-rasāmṛta-sindhu 1.2.256) Although Māyāvādī philosophers say that the material creation is false, actually it is not false; it is factual, but the idea that everything belongs to human society is false. Everything belongs to the Supreme Personality of Godhead, for everything is created by Him. All living entities, being the Lord's sons, His eternal parts and parcels, have the right to use their father's property by nature's arrangement. As stated in the Upaniṣads, tena tyaktena bhuñjīthā mā gṛdhaḥ kasya svid dhanam . Everyone should be satisfied with the things allotted him by the Supreme Personality of Godhead; no one should encroach upon another's rights or property.
(Srimad Bhagavatam-----7:14:7-----purport).

In this verse the words ānantyam icchatā refer to persons who desire to achieve liberation from material bondage and merge into the existence of the Lord. Devotees, however, whose objective is to associate personally with the Lord, have no desire to accept the activities of karma-kāṇḍa or jñāna-kāṇḍa, for pure devotional service is above both karma-kāṇḍa and jñāna-kāṇḍa. Anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam (Bhakti-rasāmṛta-sindhu 1.1.11). In pure devotional service there is not even a pinch of jñāna or karma. Consequently, when Vaiṣṇavas distribute charity, they do not need to find a brāhmaṇa performing the activities of jñāna-kāṇḍa or karma-kāṇḍa. The best example in this regard is provided by Advaita Gosvāmī, who, after performing the śrāddha ceremony for his father, offered charity to Haridāsa Ṭhākura, although it was known to everyone that Haridāsa Ṭhākura was born in a Mohammedan family, not a brāhmaṇa family, and was not interested in the activities of jñāna-kāṇḍa or karma-kāṇḍa.
(Srimad Bhagavatam-----7:15:2-----purport).

It doesn't matter whether a person is born as a śūdra, a woman or a vaiśya; if he associates with devotees repeatedly or always (sādhu-saṅgena), he can be elevated to the highest perfection. Nārada Muni is explaining this in relation to his own life. The saṅkīrtana movement is important, for regardless of whether one is a śūdra, vaiśya, mleccha, yavana or whatever, if one associates with a pure devotee, follows his instructions and serves the pure devotee, his life is successful. This is bhakti. Ānukūlyena kṛṣṇānuśīlanam (CC.2:19:167). Bhakti consists of serving Kṛṣṇa and His devotees very favorably. Anyābhilāṣitā-śūnyam (Bhakti-rasāmṛta-sindhu 1.1.11). If one has no desire other than to serve Kṛṣṇa and His devotee, then his life is successful. This is explained by Nārada Muni through this practical example from his own life.
(Srimad Bhagavatam-----7:15:73-----purport).

The Gopāla-tāpanī Upaniṣad (15) says, bhaktir asya bhajanaṁ tad ihāmutropādhi-nairāsyenaivāmuṣmin manasaḥ kalpanam etad eva ca naiṣkarmyam. This is a definition of naiṣkarmya. One acts in naiṣkarmya when he fully engages in Kṛṣṇa conscious activities without material desires to enjoy, either here or in the upper planetary systems, in the present life or in a future life (iha-amutra). Anyābhilāṣitā-śūnyam (Bhakti-rasāmṛta-sindhu 1.1.11). When one is freed from all contamination and he acts in devotional service under the direction of the spiritual master, one is on the platform of naiṣkarma. By such transcendental devotional service, the Lord is served. I offer my respectful obeisances unto Him.
(Srimad Bhagavatam-----8:3:11-----purport).

If one is favored by the Supreme Personality of Godhead by having his gross body touched by the Lord, his body turns into a spiritual body, and he can go back home, back to Godhead. Gajendra assumed a spiritual body when his body was touched by the Lord. Similarly, Dhruva Mahārāja assumed his spiritual body in this way. Arcanā-paddhati, daily worship of the Deity, provides an opportunity to touch the body of the Supreme Personality of Godhead, and thus it enables one to be fortunate enough to get a spiritual body and go back to Godhead. Not only by touching the body of the Supreme Lord, but simply by hearing about His pastimes, chanting His glories, touching His feet and offering worship—in other words, by serving the Lord somehow or other—one is purified of material contamination. This is the result of touching the Supreme Lord. One who is a pure devotee (anyābhilāṣitā-śūnyam (Bhakti-rasāmṛta-sindhu 1.1.11)), who acts according to the śāstra and the words of the Supreme Personality of Godhead, certainly becomes purified. Like Gajendra, he assumes a spiritual body and returns home, back to Godhead.
(Srimad Bhagavatam-----8:4:6-----purport).

One is in the material world when he thinks, "I am this body, and everything with reference to my body is mine." Ato gṛha-kṣetra-sutāpta-vittair janasya moho 'yam ahaṁ mameti (S.B.5:5:8). This is the symptom of material life. In the materialistic conception of life, one thinks, "This is my house, this is my land, this is my family, this is my state," and so on. But those who are munayaḥ, saintly persons following in the footsteps of Nārada Muni, simply engage in the transcendental loving service of the Lord without any personal desire for sense gratification. Anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam (Bhakti-rasāmṛta-sindhu 1.1.11).
(Srimad Bhagavatam-----8:12:6-----purport).

"Things should be accepted for the Lord's service and not for one's personal sense gratification. If one accepts something without attachment and accepts it because it is related to Kṛṣṇa, one's renunciation is called yuktaṁ vairāgyam. Whatever is favorable for the rendering of service to the Lord should be accepted and should not be rejected as a material thing." (Bhakti-rasāmṛta-sindhu 1.2.255-256) The jagat should not be rejected as mithyā. It is truth, and the truth is realized when everything is engaged in the service of the Lord.
(Srimad Bhagavatam-----8:12:8-----purport).

"Devotional service of the Lord that ignores the authorized Vedic literatures like the Upaniṣads, purāṇas and Nārada Pañcarātra is simply an unnecessary disturbance in society." (Bhakti-rasāmṛta-sindhu 1.2.101) Those who are very advanced in knowledge and are situated in the mode of goodness follow the Vedic instructions of the śruti and smṛti and other religious scriptures, including the pāñcarātrikī-vidhi. Without understanding the Supreme Personality of Godhead in this way, one only creates a disturbance. In this age of Kali, so many gurus have sprung up, and because they do not refer to the śruti-smṛti-purāṇādi-pañcarātrika-vidhi, they are creating a great disturbance in the world in regard to understanding the Absolute Truth. However, those who follow the pāñcarātrikī-vidhi under the guidance of a proper spiritual master can understand the Absolute Truth. It is said, pañcarātrasya kṛtsnasya vaktā tu bhagavān svayam: the pañcarātra system is spoken by the Supreme Personality of Godhead, just like Bhagavad-gītā. Vāsudeva-śaraṇā vidur añjasaiva: the truth can be understood only by one who has taken shelter of the lotus feet of Vāsudeva.
