"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)
One should not be attached to material opulence, but material opulence may be accepted in the Kṛṣṇa consciousness movement to facilitate the propagation of the movement. In other words, material opulence may be accepted as yukta-vairāgya, that is, for renunciation.
(Srimad Bhagavatam------4:29:55-----purport).

"One who engages in the transcendental service of the Lord in body, mind and words is to be considered liberated in all conditions of material existence." (Bhakti-rasāmṛta-sindhu 1.2.187) The Kṛṣṇa consciousness movement is based on this principle. We must teach people to absorb themselves always in the service of the Lord because that position is their natural position. One who is always serving the Lord is to be considered already liberated. This is also confirmed in Bhagavad-gītā (14.26):
māṁ ca yo 'vyabhicāreṇa
bhakti-yogena sevate
sa guṇān samatityaitān
brahma-bhuyāya kalpate
"One who always engages in the spiritual activities of unalloyed devotional service at once transcends the modes of material nature and is elevated to the spiritual platform." The devotee is therefore above the three modes of material nature and is even transcendental to the brāhmaṇa platform. A brāhmaṇa may be infected by the two baser modes—namely rajo-guṇa and tamo-guṇa. A pure devotee, who is free from all material desires experienced on the mental platform and who is also free from empiric philosophical speculation or fruitive activity, is always above material conditioning and is always liberated.
(Srimad Bhagavatam------4:29:65-----purport).

One who tries to enjoy the results of his activities becomes bound by the results. One who offers the results or profits to the Supreme Personality of Godhead, however, does not become entangled in the results. This is the secret of success. Generally people take sannyāsa to become free from the reactions of fruitive activity. One who does not receive the results of his actions but offers them instead to the Supreme Personality of Godhead certainly remains in a liberated condition. In Bhakti-rasāmṛta-sindhu, Śrī Rūpa Gosvāmī confirms this:
īhā yasya harer dāsye
karmaṇā manasā girā
nikhilāsv apy avasthāsu
jīvan-muktaḥ sa ucyate
If one engages himself in the service of the Lord through his life, wealth, words, intelligence and everything he possesses, he will always be liberated in any condition. Such a person is called a jīvan-mukta, one who is liberated during this lifetime. Devoid of Kṛṣṇa consciousness, those who engage in material activities simply become more entangled in material bondage. They have to suffer and enjoy the actions and reactions of all activity. This Kṛṣṇa consciousness movement is therefore the greatest boon to humanity because it keeps one always engaged in Kṛṣṇa's service. The devotees think of Kṛṣṇa, act for Kṛṣṇa, eat for Kṛṣṇa, sleep for Kṛṣṇa and work for Kṛṣṇa. Thus everything is engaged in the service of Kṛṣṇa.
(Srimad Bhagavatam------4:30:19-----purport).

In Bhakti-rasāmṛta-sindhu it is said that by executing devotional service to the Lord, one can understand the transcendental position of the living being and the Supreme Personality of Godhead. The Supreme Personality of Godhead cannot be understood by any means except bhakti. The Lord confirms this in Śrīmad-Bhāgavatam (11.14.21). Bhaktyāham ekayā grāhyaḥ: "only by executing devotional service can one appreciate Me." Similarly, in Bhagavad-gītā (18.55) Lord Kṛṣṇa says, bhaktyā mām abhijānāti: "simply by discharging devotional service, one can understand Me." Thus for a bhakta to become attached to family affairs is impossible, since a bhakta and his associates are liberated. Everyone is searching after ānanda, or bliss, but in the material world there can never be any bliss. It is only possible in devotional service. Attachment for family affairs and devotional service are incompatible. Therefore Mahārāja Parīkṣit was somewhat surprised to hear that Mahārāja Priyavrata was simultaneously attached to devotional service and to family life.
(Srimad Bhagavatam------5:1:2-----purport).

Brahmā's purpose was to break Priyavrata's determination. Therefore Brahmā first looked upon Priyavrata with compassion. His smile and compassionate features also indicated that although Brahmā would request Priyavrata to accept household life, Priyavrata would not be out of touch with devotional service. By the blessings of a Vaiṣṇava, everything is possible. This is described in Bhakti-rasāmṛta-sindhu as kṛpā-siddhi, or perfection attained simply by the blessings of a superior person. One usually becomes liberated and perfect by executing the regulative principles set down in the śāstras. Nonetheless, many persons have achieved perfection simply by the blessings of a spiritual master or superior.
(Srimad Bhagavatam------5:1:10-----purport).

Although Ṛṣabhadeva had nothing to learn from gurukula, He went there just to teach the people in general how to take an education from the right source, from Vedic teachers. He then entered householder life and lived according to the principles of Vedic knowledge—śruti and smṛti. In his Bhakti-rasāmṛta-sindhu (1.2.101) Śrīla Rūpa Gosvāmī, quoting the Skanda Purāṇa, states:
śruti-smṛti-purāṇādi-
pañcarātra-vidhiṁ vinā
aikāntikī harer bhaktir
utpātāyaiva kalpate
(Brs. 1.2.101)
Human society must follow the instructions received from śruti and smṛti, Vedic literature. Practically applied in life this is worship of the Supreme Personality of Godhead according to the pāñcarātrika-vidhi. Every human being must advance his spiritual life and at the end return home, back to Godhead. Mahārāja Ṛṣabhadeva strictly followed all these principles. He remained an ideal gṛhastha and taught His sons how to become perfect in spiritual life. These are some examples of how He ruled the earth and completed His mission as an incarnation.
(Srimad Bhagavatam------5:4:8-----purport).

In these four verses, Ṛṣabhadeva tells His sons how they can be freed from the false identification arising from false ego and material conditional life. One gradually becomes liberated by practicing as mentioned above. All these prescribed methods enable one to give up the material body (liṅgaṁ vyapohet) and be situated in his original spiritual body. First of all one has to accept a bona fide spiritual master. This is advocated by Śrīla Rūpa Gosvāmī in his Bhakti-rasāmṛta-sindhu: śrī-guru-pādāśrayaḥ. To be freed from the entanglement of the material world, one has to approach a spiritual master. Tad-vijñānārthaṁ sa gurum evābhigacchet (MU 1.2.12). By questioning the spiritual master and by serving him, one can advance in spiritual life. When one engages in devotional service, naturally the attraction for personal comfort—for eating, sleeping and dressing—is reduced. By associating with the devotee, a spiritual standard is maintained. The word mad-deva-saṅgāt is very important. There are many so-called religions devoted to the worship of various demigods, but here good association means association with one who simply accepts Kṛṣṇa as his worshipable Deity.
(Srimad Bhagavatam------5:5:10-13-----purport).

This argument offered by Mahārāja Rahūgaṇa is certainly very effective. In his Bhakti-rasāmṛta-sindhu (1.2.4), Śrīla Rūpa Gosvāmī says, tasmāt kenāpy upāyena manaḥ kṛṣṇe niveśayet: (S.B.7:1:32) somehow or other, one should engage in Kṛṣṇa consciousness. Actually every living being is an eternal servant of Kṛṣṇa, but due to forgetfulness, a living entity engages himself as an eternal servant of māyā. As long as one is engaged in māyā's service, he cannot be happy. Our Kṛṣṇa consciousness movement aims at engaging people in Lord Kṛṣṇa's service. That will help them become freed from all material contamination and sinful activity. This is confirmed in Bhagavad-gītā (4.10): vīta-rāga-bhaya-krodhāḥ. By becoming detached from material activities, we will be freed from fear and anger. By austerity, one becomes purified and eligible to return home, back to Godhead.
(Srimad Bhagavatam------5:10:23-----purport).

"One who acts to serve Kṛṣṇa with his body, mind, intelligence and words is a liberated person, even within this material world." (Bhakti-rasāmṛta-sindhu 1.2.187) A person who always desires to serve Kṛṣṇa is interested in ways to convince people that there is a Supreme Personality of Godhead and that the Supreme Personality of Godhead is Kṛṣṇa. That is his ambition. It doesn't matter whether he is in heaven or in hell. This is called uttamaśloka-lālasa.
(Srimad Bhagavatam------5:14:44-----purport).

The universal form is certainly material, but because everything is an expansion of the energy of the Supreme Personality of Godhead, ultimately nothing is material. Therefore Parīkṣit Mahārāja's mind was saturated with spiritual consciousness. Śrīla Rūpa Gosvāmī has stated:
prāpañcikatayā buddhyā
hari-sambandhi-vastunaḥ
mumukṣubhiḥ parityāgo
vairāgyaṁ phalgu kathyate
(Bhakti-rasāmṛta-sindhu 1.2.255-256)
Everything, even that which is material, is connected with the Supreme Personality of Godhead. Therefore everything should be engaged in the service of the Lord.
(Srimad Bhagavatam------5:16:3-----purport).
