Attachment for household paraphernalia and for Lord Kṛṣṇa go poorly together. One attachment is the path of darkness, and the other attachment is the path of light. Where there is light, there is no darkness, and where there is darkness, there is no light. But an expert devotee can turn everything to the path of light by an attitude of service to the Lord, and the best example here is the Pāṇḍavas. Mahārāja Yudhiṣṭhira and householders like him can turn everything to light by dovetailing so-called material assets in the service of the Lord, but one who is not trained or is unable to turn everything to the service of the Lord (nirbandhaḥ kṛṣṇa-sambandhe) must give up all material connections before he can be fit to hear and chant the glories of the Lord, or in other words, one who has seriously heard Śrīmad-Bhāgavatam for even one day, like Mahārāja Parīkṣit, from a fit personality like Śukadeva Gosvāmī, may be able to lose all affinity for material things.
(Srimad Bhagavatam----2:2:4----purport).

This humbleness of the pure devotee, who is one hundred percent engaged in His service, puts the devotee of the Lord in a trance by which to realize everything, because to the sincere devotee of the Lord, the Lord reveals Himself, as stated in the Bhagavad-gītā (10.10). The Lord, being the Lord of intelligence in everyone (even in the nondevotee), favors His devotee with proper intelligence so that automatically the pure devotee is enlightened with the factual truth about the Lord and His different energies. the Lord is revealed not by one's speculative power or by one's verbal jugglery over the Absolute Truth. Rather, He reveals Himself to a devotee when He is fully satisfied by the devotee's service attitude. Śukadeva Gosvāmī is not a mental speculator or compromiser of the theory of "as many ways, as many conclusions." Rather, he prays to the Lord only, invoking His transcendental pleasure. That is the way of knowing the Lord.
(Srimad Bhagavatam----2:4:21----purport).

The Lord is not approachable by everyone because He is curtained by His yogamāyā potency. But one should not wrongly conclude that the Lord was formerly unmanifested and has now manifested Himself in the human form. This misconception of the formlessness of the Supreme Personality of Godhead is due to the yogamāyā curtain of the Lord and can be removed only by the Supreme Will, as soon as the conditioned soul surrenders unto Him. The devotees of the Lord who are transcendental to the above-mentioned three modes of material nature can see the all-blissful transcendental form of the Lord with their vision of love in the attitude of pure devotional service.
(Srimad Bhagavatam----2:5:20----purport).

Beginning from Satyaloka, the topmost planet of the universe, situated just below the eternal Brahmaloka, as described above, all the planets are material. And one's situation in any of the many material planets is still subject to the laws of material nature, namely birth, death, old age and disease. But one can get complete liberation from all the above-mentioned material pangs when one enters into the eternal Brahmaloka sanātana atmosphere, the kingdom of God. Therefore liberation, as contemplated by the speculative philosophers and the mystics, is possible only when one becomes a devotee of the Lord. Anyone who is not a devotee cannot enter into the kingdom of God. Only by attainment of a service attitude in the transcendental position can one enter into the kingdom of Godhead. Therefore the speculative philosophers, as well as the mystics, must first of all be attracted to the devotional cult before they can factually attain liberation.
(Srimad Bhagavatam----2:5:40-41----purport).

Transcendental service to the Lord is not mundane. The service attitude of the devotee gradually increases and never becomes slackened. Generally, in old age a person is allowed retirement from mundane service. But in the transcendental service of the Lord there is no retirement at all; on the contrary, the service attitude increases more and more with the progress of age. In the transcendental service there is no satiation, and therefore there is no retirement. Materially, when a man becomes tired by rendering service in his physical body, he is allowed retirement, but in the transcendental service there is no feeling of fatigue because it is spiritual service and is not on the bodily plane. Service on the bodily plane dwindles as the body grows older, but the spirit is never old, and therefore on the spiritual plane the service is never tiresome.
(Srimad Bhagavatam----3:2:3----purport).

Uddhava undoubtedly became old, but that does not mean that his spirit became old. His service attitude matured on the transcendental plane, and therefore as soon as he was questioned by Vidura about Lord Kṛṣṇa, he at once remembered his Lord by reference to the context and forgot himself on the physical plane. That is the sign of pure devotional service to the Lord, as will be explained later on (lakṣaṇaṁ bhakti-yogasya, etc.) in Lord Kapila's instructions to His mother, Devahūti.
(Srimad Bhagavatam----3:2:3----purport).

Service is the real constitutional occupation of all living entities. The living entities are meant to render service to the Lord, and they can attain religious perfection by this service attitude. One cannot attain religious perfection simply by speculating to attain theoretical knowledge. The jñānī division of spiritualists go on speculating only to distinguish the soul from matter, but they have no information of the activities of the soul after being liberated by knowledge. It is said that persons who only mentally speculate to know things as they are and who do not engage in the transcendental loving service of the Lord are simply wasting their time.
(Srimad Bhagavatam----3:6:33----purport).

It is actually better to be a śūdra than to be a brāhmaṇa and not develop the service attitude, because that attitude alone satisfies the Lord. Every living being—even if he be a brāhmaṇa by qualification—must take to the transcendental service of the Lord. Both Bhagavad-gītā and the Śrīmad-Bhāgavatam support that this service attitude is the perfection of the living entity. A brāhmaṇa, kṣatriya, vaiśya or śūdra can perfect his occupational duties only by rendering service unto the Lord.
(Srimad Bhagavatam----3:6:33----purport).

A brāhmaṇa is supposed to know this fact due to his perfection in Vedic wisdom. The other sections are supposed to follow the direction of the brāhmaṇa Vaiṣṇava (one who is a brāhmaṇa by qualification and a Vaiṣṇava by action). That will make the entire society perfect in regard to the order of its social construction. A disordered society cannot satisfy either the members of the society or the Lord. Even if one is not a perfect brāhmaṇa, kṣatriya, vaiśya or śūdra but takes to the service of the Lord, not caring for the perfection of his social position, he becomes a perfect human being simply by developing the attitude of service to the Supreme Lord.
