Śrīla Madhvācārya quotes the following verse from the Brahmāṇḍa Purāṇa:
jñānānandātmano viṣṇuḥ
śiśumāra-vapuṣy atha
ūrdhva-lokeṣu sa vyāpta
ādityādyās tad-āśritā
Lord Viṣṇu, who is the source of knowledge and transcendental bliss, has assumed the form of Śiśumāra in the seventh heaven, which is situated in the topmost level of the universe. All the other planets, beginning with the sun, exist under the shelter of this Śiśumāra planetary system.
(Srimad Bhagavatam-----5:22:17----purport).

The Lord says in Bhagavad-gītā (B.G.10:8):
ahaṁ sarvasya prabhavo
mattaḥ sarvaṁ pravartate
iti matvā bhajante māṁ
budhā bhāva-samanvitāḥ
"I am the source of all spiritual and material worlds. Everything emanates from Me. The wise who perfectly know this engage in My devotional service and worship Me with all their hearts." In Śrīmad-Bhāgavatam (S.B.2:9:33) the Lord also says, aham evāsam evāgre: "Only I existed before the creation." This is confirmed in the Brahmāṇḍa Purāṇa as follows:
smṛtir avyavadhānena
prakṛtitvam iti sthitiḥ
ubhayātmaka-sūtitvād
vāsudevaḥ paraḥ pumān
prakṛtiḥ puruṣaś ceti
śabdair eko 'bhidhīyate
To generate the universe, the Lord acts indirectly as the puruṣa and directly as the prakṛti. Because both energies emanate from Lord Vāsudeva, the all-pervasive Supreme Personality of Godhead, He is known as both prakṛti and puruṣa. Therefore Vāsudeva is the cause of everything (sarva-kāraṇa-kāraṇam (Bs. 5.1)).
(Srimad Bhagavatam-----6:9:26-27----purport).

Because of the poisonous effects of Kali-yuga, the śāstra (S.B.12:2:13) says, dasyu-prāyeṣu rājasu: the government will adopt the policies of dasyus, or plunderers. Thus there will be no instructions from the brāhmaṇas, and even if there are brahminical instructions, there will be no kṣatriya rulers who can follow them. Aside from Satya-yuga, even formerly, in the days when demons were flourishing, Hiraṇyakaśipu planned to destroy the brahminical culture and the kṣatriya government and thus create chaos all over the world. Although in Satya-yuga this plan was very difficult to execute, in Kali-yuga, which is full of śūdras and demons, the brahminical culture is lost and can be revived only by the chanting of the mahā-mantra. Therefore the Kṛṣṇa consciousness movement, or the Hare Kṛṣṇa movement, has been inaugurated to revive brahminical culture very easily so that people may become happy and peaceful in this life and prepare for elevation in the next. In this regard, Śrīla Madhvācārya quotes this verse from the Brahmāṇḍa Purāṇa:
vipra-yajñādi-mūlaṁ tu
harir ity āsuraṁ matam
harir eva hi sarvasya
mūlaṁ samyaṅ mato nṛpa
"O King, the demons think that Hari, Lord Viṣṇu, exists because of the brāhmaṇas and yajña, but factually Hari is the cause of everything including the brāhmaṇas and yajña." Therefore, through the popularizing of hari-kīrtana, or the saṅkīrtana movement, the brahminical culture and kṣatriya government will automatically come back, and people will be extremely happy.
(Srimad Bhagavatam-----7:2:11----purport).

In other places, the following offenses are listed: (a) to be against the scriptural injunctions of the Vedic literature or to disrespect within one's heart the Śrīmad-Bhāgavatam while externally falsely accepting its principles, (b) to introduce differing śāstras, (c) to chew pan and betel before the Deity, (d) to keep flowers for worship on the leaf of a castor oil plant, (e) to worship the Deity in the afternoon, (f) to sit on the altar or to sit on the floor to worship the Deity (without a seat), (g) to touch the Deity with the left hand while bathing the Deity, (h) to worship the Deity with a stale or used flower, (i) to spit while worshiping the Deity, (j) to advertise one's glory while worshiping the Deity, (k) to apply tilaka to one's forehead in a curved way, (l) to enter the temple without having washed one's feet, (m) to offer the Deity food cooked by an uninitiated person, (n) to worship the Deity and offer bhoga to the Deity within the vision of an uninitiated person or non-Vaiṣṇava, (o) to offer worship to the Deity without worshiping Vaikuṇṭha deities like Gaṇeśa, (p) to worship the Deity while perspiring, (q) to refuse flowers offered to the Deity, (r) to take a vow or oath in the holy name of the Lord.
If one commits any of the above offenses, one must read at least one chapter of Bhagavad-gītā. This is confirmed in the Skanda-Purāṇa, Avantī-khaṇḍa. Similarly, there is another injunction, stating that one who reads the thousand names of Viṣṇu can be released from all offenses. In the same Skanda-Purāṇa, Revā-khaṇḍa, it is said that one who recites prayers to tulasī or sows a tulasī seed is also freed from all offenses. Similarly, one who worships the śālagrāma-śilā can also be relieved of offenses. In the Brahmaṇḍa Purāṇa it is said that one who worships Lord Viṣṇu, whose four hands bear a conchshell, disc, lotus flower and club, can be relieved from the above offenses.
(Srimad Bhagavatam-----7:5:23-24----purport).

In the Brahmāṇḍa Purāṇa it is said, "The same Personality of Godhead who is known in Vaikuṇṭha as the four-handed Nārāyaṇa, the friend of all living entities, and in the milk ocean as the Lord of Śvetadvīpa, and who is the best of all puruṣas, appeared as the son of Nanda. In a fire there are many sparks of different dimensions; some of them are very big, and some are small. The small sparks are compared to the living entities, and the large sparks are compared to the Viṣṇu expansions of Lord Kṛṣṇa. All the incarnations emanate from Kṛṣṇa, and after the end of their pastimes they again merge with Kṛṣṇa."
(Sri Caitanya Caritamrta-----1:5:132-----purport).

In the Brahmāṇḍa Purāṇa it is said:
siddha-lokas tu tamasaḥ pāre yatra vasanti hi
siddhā brahma-sukhe magnā daityāś ca hariṇā hatāḥ
"In Siddhaloka (Brahmaloka) there live two kinds of living entities—those who are killed by the Supreme Personality of Godhead due to their having been demons in their previous lives and those who are very fond of enjoying the impersonal effulgence of the Lord."
(Sri Caitanya Caritamrta-----2:6:263-----purport).

In the Brahmāṇḍa Purāṇa it is said, "A person who sees the Lord's Ratha-yātrā car festival and then stands up to receive the Lord can purge all kinds of sinful results from his body."
(Nectar of Devotion).

In the Varāha Purāṇa there is a statement praising the residential quarters of Mathurā. Lord Varāha tells the men of earth, "Any person who becomes attracted to places other than Mathurā will certainly be captivated by the illusory energy." In the Brahmāṇḍa Purāṇa it is said that all the results of traveling on all the pilgrimages within the three worlds can be achieved simply by touching the holy land of Mathurā. In many śāstras (scriptures) it is said that simply by hearing, remembering, glorifying, desiring, seeing or touching the land of Mathurā, one can achieve all desires.
(Nectar of Devotion).

In the Brahmāṇḍa Purāṇa it is stated, "Those who have achieved liberation from material contamination and those who are demons and are killed by the Supreme Personality of Godhead become absorbed in the Brahman concept of life and reside in the spiritual sky of the brahmajyoti." That spiritual sky is far beyond the material sky, and it is confirmed also in Bhagavad-gītā that beyond this material sky there is another, eternal sky.
