Original eternally perfect devotees

atha nitya-siddhāḥ -
ātma-koṭi-guṇaṁ kṛṣṇe premāṇaṁ paramaṁ gatāḥ |
nityānanda-guṇāḥ sarve nitya-siddhā mukundavat ||2.1.290||

"Those whose very body and qualities are bliss like Mukunda's,
and who possess the highest prema for Kṛṣṇa,
which is ten million times greater than the attachment for the self
are called already eternally perfect (nitya-siddha)."

yathā pādme śrī-bhagavat-satyabhāmā-devī-saṁvāde -
atha brahmādi-devānāṁ tathā prārthanayā bhuvaḥ |
āgato'haṁ gaṇāḥ sarve jātās te'pi mayā saha ||2.1.291||

ete hi yādavāḥ sarve mad-gaṇā eva bhāmini |
sarvadā mat-priyā devi mat-tulya-guṇa-śālinaḥ ||2.1.292||

An example from the discussion between Satyabhāmā and the Lord, from the Padma Purāṇa:
"O beautiful Satyabhāmā! I have come because of the prayers of Brahmā and
the devatās, and My associates all have taken birth with Me.

The Yādavas that you see are all My associates and are full of all qualities like Mine.
They always hold Me alone as dear."

tathā ca śrī-daśame (10.14.32) -
aho bhāgyam aho bhāgyaṁ nanda-gopa-vrajaukasām |
yan-mitraṁ paramānandaṁ pūrṇaṁ brahma sanātanam ||2.1.293||

Another example from the Tenth Canto of Śrīmad-Bhāgavatam [10.14.32]:
"How greatly fortunate are Nanda Mahārāja, the cowherd men
and all the other inhabitants of Vrajabhūmi!

There is no limit to their good fortune, because the Absolute Truth,
the source of transcendental bliss, the eternal Supreme Brahman, is their eternal friend."

tatraiva (10.26.13) -
dustyajaś cānurāgo'smin sarveṣāṁ no vrajaukasām |
nanda te tanaye'smāsu tasyāpy autpattikaḥ katham ||2.1.294||

Also from the Tenth Canto of Śrīmad-Bhāgavatam [10.26.13]:
"Dear Nanda, how is it that we and all the other residents of Vraja
cannot give up our constant affection for your son?
And how is it that He is so attracted to us?"

sanātanaṁ mitram iti tasyāpy autpattikaḥ katham |
sneho'smāsv iti caiteṣāṁ nitya-preṣṭhatvam āgatam ||2.1.295||

"One can understand that the inhabitants of Vraja are eternal associates of the Lord
by the words 'eternal friend' in verse 293 and 'how is it that He is so attracted to us?' in verse 294."

ity ataḥ kathitā nitya-priyā yādava-vallavāḥ |
eṣāṁ laukikavac-ceṣṭā līlā mura-ripor iva ||2.1.296||

"Thus for this reason, the Yādavas known as the cowherd people
are said to be eternal associates of the Lord.

As with the Lord's actions, their actions also appear worldly,
although everything about them is purely spiritual."

tathā hi pādmottara-khaṇḍe -
yathā saumitri-bharatau yathā saṅkarṣaṇādayaḥ |
tathā tenaiva jāyante nija-lokād yadṛcchayā ||2.1.297||
punas tenaiva gacchanti tat-padaṁ śāśvataṁ param |
na karma-bandhanaṁ janma vaiṣṇavānāṁ ca vidyate ||2.1.298||

Also, from the Uttara-khaṇḍa of the Padma Purāṇa:
"Just as Lakṣmaṇa, Bharata and Saṅkarṣana take birth with the Lord,
the Yādava cowherd people, descending from their spiritual planet by the Lord's will,
take birth with the appearance of Lord Kṛṣṇa,
and then return to His eternal dhāma along with Him.
The birth of these devotees is not caused by bondage to karma."
