Śrimad-Bhāgavatam
[Canto 10, Ch. 10]
PURPORT
A tree has no consciousness: when cut, it feels no pain. But Nārada Muni wanted the consciousness of Nalakūvara and Maṇigrīva to continue, so that even after being released from the life of trees, they would not forget the circumstances under which they had been punished. Therefore, to bestow upon them special favor, Nārada Muni arranged things in such a way that after being released, they would be able to see Kṛṣṇa in Vṛndāvana and thus revive their dormant  bhakti .
Each day of the demigods in the upper planetary system equals six months of our measurement. Although the demigods in the upper planetary system are attached to material enjoyment, they are all devotees, and therefore they are called demigods. There are two kinds of persons, namely the  devas  and the  asuras .  Asuras  forget their relationship with Kṛṣṇa ( āsuraṁ bhāvam āśritāḥ ), whereas the  devas  do not forget.
dvau bhūta-sargau loke 'smin daiva āsura eva ca viṣṇu-bhaktaḥ smṛto daiva āsuras tad-viparyayaḥ (Padma Purāṇa)
The distinction between a pure devotee and a  karma-miśra  devotee is this: a pure devotee does not desire anything for material enjoyment, whereas a mixed devotee becomes a devotee to become a first-class enjoyer of this material world. One who is in direct touch with the Supreme Personality of Godhead in devotional service remains pure, uncontaminated by material desires ( anyābhilāṣitā-śūnyaṁ jñāna-karmādyanāvṛtam ).
By  karma-miśra-bhakti  one is elevated to the celestial kingdom, by  jñāna-miśra-bhakti  one is able to merge in the Brahman effulgence, and by  yoga-miśra-bhakti  one is able to realize the omnipotency of the Supreme Personality of Godhead. But pure  bhakti  does not depend on  karma ,  jñāna  or  yoga , for it simply consists of loving affairs. The liberation of the  bhakta , therefore, which is called not just  mukti  but  vimukti , surpasses the five other kinds of liberation— sāyujya ,  sārūpya ,  sālokya ,  sārṣṭi  and  sāmīpya . A pure devotee always engages in pure service
