A self-realized person, or a devotee, knows well that this material cosmic manifestation is a temporary, illusory representation appearing to be truth. It is like a phantasmagoria. But behind this shadow creation there is reality – the spiritual world. A devotee is interested in the spiritual world, not its shadow. Since he has realization of the supreme truth, a devotee is not interested in this temporary shadow of truth.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 4.12.15, Purport
One should learn how to associate with the devotees of the Lord by gathering with them to chant the glories of the Lord. This process is most purifying. As devotees thus develop their loving friendship, they feel mutual happiness and satisfaction. And by thus encouraging one another they are able to give up material sense gratification, which is the cause of all suffering.
Lord Sri Krishna
Srimad-Bhagavatam 11.3.30
The . . . jiva is eternal and is for eternity and without a beginning joined to the Supreme Lord by the tie of an eternal kinship. He is transcendental spiritual potency.
Sri Brahma-samhita 5.21
The Lord, full of knowledge and bliss, is situated in bhakti-yoga, which is also eternity, knowledge, and bliss.
Gopala-tapani Upanishad 2.78
Material maya, the controller of all beings in the material world, is the covering energy of yoga-maya. By her the whole universe becomes bewildered and everyone thinks they are their bodies.
Sruti-vidya
Narada-pancaratra
When those in hell chant the name of the Lord, they develop bhakti to the Lord and go to the spiritual world.
Nrisimha Purana
O Lord [Krishna], O killer of the Agha demon, may we find happiness in the deep ocean of Your transcendental pastimes, where the great waves of Your smiles and laughter rock the universes, where the center is always crowded with many dolphins of the surrendered souls, and where the swans of the great devotees drink to their full satisfaction.
Srila Bhaktivinoda Thakura
Sri Govinda-virudavali 7
One hundred generations forward and one hundred generations backward of a family in which a maha-bhagavata [topmost devotee] appears are automatically delivered. Fourteen generations forward and fourteen generations backward of a family in which a madhyama-adhikari [intermediate devotee] appears are automatically delivered. Three generations forward and three generations backward of a family in which a kanishtha-adhikari [neophyte devotee] appears are delivered.
