3-Residents of Vaikuntha have perfect qualities, are fully satisfied (desireless) and there is no disharmony

The following quotes substantiate that there is no possibility of emnity between the Lord and His personal associates in the spiritual world. Envy and disharmony are nonexistent there. The eternal residents are completely satisfied and all their desires are satisfied by rendering service to the Lord.

Sastric texts:

In the Vaikuntha world there is complete harmony between the residents and the Supreme Personality of Godhead. (Bhag. 3.15.33, text)

And in the spiritual world every living entity is called infallible. (Bg.15.16, text)

Srila Rupa Goswami:

All the eternally perfected devotees have eternal and blissful qualities just like Lord Mukunda. Their supreme love for Krsna is millions and missions of times more than their love for their own self or body. (Brs. 2.1.290)

Srila Jiva Goswami:

According to Srila Jiva Gosvami, the so-called fight among the members of the Yadu dynasty was actually a display of the pastime potency of the Lord, since Lord Krsna's personal associates are never subject to ordinary birth and death like conditioned souls. (Bhag. 11.31.11, purport)

Srila A. C. Bhaktivedanta Swami Prabhupada:

In Vaikunthaloka there is no occupation but the service of the Lord, and this service is not rendered with a purpose. Although every service has a particular result, the devotees never aspire for the fulfillment of their own desires; their desires are fulfilled by rendering transcendental loving service to the Lord. (Bhag. 3.15.14, purport)

In the Vaikuntha world, the spiritual sky, only the mode of goodness in its pure form exists. The Lord and His devotees reside in the Vaikuntha planets, and they are of the same transcendental quality, namely, suddha-sattva, the mode of pure goodness. (Bhag. 3.15.15, purp.)

Serving the Lord in transcendental love yields such transcendental pleasure that, in comparison, sense gratification is counted as insignificant. (Bhag. 3.15.17, purp.)

The most important thing about the spiritual world is that there is no envy among the devotees there. This is true even among the flowers, which are all conscious of the greatness of tulasi. In the Vaikuntha world entered by the four Kumaras, even the birds and flowers are conscious of service to the Lord. (Bhag. 3.15.19, purp.)

The difference between the inhabitants of a Vaikuntha planet and those of a material planet is that in Vaikuntha all the residents engage in the service of the Lord Himself and are equipped with all His good qualities. It has been analyzed by great personalities that when a conditioned soul is liberated and becomes a devotee, about seventy-nine percent of all the good qualities of the Lord develop in his person. Therefore in the Vaikuntha world there is no question of enmity between the Lord and the residents. Here in this material world the citizens may be inimical to the chief executives or heads of state, but in Vaikuntha there is no such mentality. One is not allowed to enter Vaikuntha unless he has completely developed the good qualities. The basic principle of goodness is to accept subordination from the Supreme Personality of Godhead. The sages therefore, were surprised to see that the two doormen who checked them from entering the palace were not exactly like the residents of Vaikunthaloka. It may be said that a doorman's duty is to determine who should be allowed to enter the palace and who should not. But that is not relevant in this matter because no one is allowed to enter the Vaikuntha planets unless he has developed one hundred percent his mentality of devotional service to the Supreme Lord. No enemy of the Lord can enter Vaikunthaloka. (Bhag. 3.15.32, purport)

In the Vaikuntha world there is no disharmony between the Lord and the residents. Therefore God's creation in the Vaikuntha world is perfect. There is no cause of fear. The entire kingdom of God is such a completely harmonious unit that there is no possibility of emnity. Everything there is absolute . . . in the Vaikuntha planets the Lord is perfect, and the inhabitants also are perfectly engaged in the service of the Lord . . . Maya means disharmony between the living entities and the Supreme Lord, and Vaikuntha means harmony between them. (Bhag. 3.15.33, purp.)

Any material happiness is like water in a ditch, whereas the spiritual happiness eternally enjoyed in the spiritual world is like an ocean of nectar in which a devotee wants to swim. (Bhag. 6.12.22, purp.)

In the advanced stage, one falls completely in love with Krsna. This highest perfectional stage of life enables the devotee to be transferred to Krsna's abode in the spiritual sky, Goloka Vrndavana, where the devotee becomes eternally happy. (Bg. 8.28, purp.)

Here the Lord is giving, in summary, the contents of the Vedanta-sutra. He says that the living entities, who are innumerable, can be divided into two classes the fallible and the infallible. The living entities are eternally separated parts and parcels of the Supreme Personality of Godhead. When they are in contact with the material world they are called jiva-bhuta, and the Sanskrit words given here, ksarah sarvani bhutani, mean that they are fallible. Those who are in oneness with the Supreme Personality of Godhead, however, are called infallible. Oneness does not mean that they have no individuality, but that there is no disunity. (Bg. 15.16, purp.)

This description of the abode of Krsna gives us definite information of the transcendental place where not only is life eternal, blissful and full of knowledge, but . . . the qualities in Vaikuntha are a manifestation of God's internal potency, and therefore they are purely spiritual and transcendental, with no trace of material infection . . . where the five inherent qualities of the material world-namely ignorance, misery, egoism, anger and envy-are completely absent . . . the influence of maya, the total external energy, which induces us to become more and more materialistic and forget our relationship with God, is also absent there . . . the living beings in Vaikunthaloka are never forgetful of their identities: they are eternally cognizant of their relationship with God . . . There is no difference between atheists and the faithful in the Vaikuntha planets because all who settle there are freed from the material qualities, and thus suras and asuras become equally obedient loving servitors of the Lord. (Cc. Madhya-lila 5.22, purp.)

The Vrndavana-lila of Krsna is the perfect presentation of the Supreme Personality of Godhead. He's simply enjoying. And all the inhabitants of Vrndavana, the gopis, the cowherd boys, Maharaja Nanda, Yasoda, everyone is simply anxious how to make Krsna happy. They have no other business. The inhabitants of Vrndavana has no other business than to satisfy Krsna, and Krsna has no other business. Yasoda-nandana brajajana-ranjana. He's acting as the little son of Yasoda, and His only business is how to please the inhabitants of Vrndavana. Yasoda-nandana brajajana-ranjana. [710217CC.GOR]

In many places in the sastra it is stated that the Lord is completely controlled by His devotees:

The Supreme Living Being is perfect in all relations with His pure devotee. (Bhag. 1.15.4)

The Lord becomes submissive to even a very insignificant devotee because of his devotional service. (Cc. Adi-lila 7.145, text)

He comes under the control of His devotees. (Bhag. 10.9.19, text)

. . . certainly conquer Your Lordship. (Bhag. 10.14.3, text)

I am completely under the control of My devotees. (Bhag. 9.4.63, text)

The pure devotees . . . bring Me under their full control. (Bhag. 9.4.66, text)

The pure devotee is always within the core of My heart. (Bhag. 9.4.68, text)

How can I give up such devotees at any time? (Bhag. 9.4.65, text)

It is also generally accepted that the highest and most perfect devotees are the residents of the spiritual world. So, they are certainly the most dear to the Lord. Throughout sastra the spiritual world is referred to as perfect, infallible and eternally blissful.

Which is directly under the protection of My spiritual energy of unadulterated bliss. That is the ultimate perfectional goal of the living entity. (Bhag. 3.27.28-29, text)

Additionally it is stated in many places in sastra that the Lord easily excuses any offenses by His surrendered devotees:

He is so gentle that even if His servant is implicated in a great offense, He does not take it very seriously. (Brs. 2.1.138, text)

If devotees completely in love with You sometimes fall from the path of devotion, they do not fall like nondevotees, for You still protect them. (Bhag. 10.2.33, text)

If such a surrendered soul accidentally commits some sinful activity, the Supreme Personality of Godhead, who is seated within everyone's heart, immediately takes away the reaction to such sin. (Bhag. 11.5.42, text)

Declare it boldly that My devotee will never perish. (Bhag.-gita 9.31)

Characteristically, the Supreme Personality of Godhead does not take seriously an offense committed by a pure devotee. (Cc. Antya-lila 1.107, text)

Even if His servant is implicated in a great offense, He does not take it very seriously. (Cc. Antya-lila 1.108, text)

To the eternal servitors of the Lord, the Lord is pleased to give all protection at all times. (Bhag. 1.14.32-3, purp.)

The Lord is equal in behavior to all living beings, but He is partial to His pure devotees, being very affectionate toward them. (Bhag. 1.14.38)

The Lord can tolerate insults upon Himself by any miscreant because the father tolerates even insults from the son. But He never tolerates insults upon His devotees. (Bhag. 1.15.10, purp.)

The Lord cannot tolerate any inconvenience on the part of the devotee. He is therefore famous as bhakta-vatsala. (Bhag. 3.16.7, purp.)

To conclude that the Lord has allowed or arranged for an uncountably huge number of dear associates of His to systematically and continuously fall from the spiritual world (His perfect abode) to hellish repeated mundane births is illogical and ridiculous, in view of the above references.
