A pure devotee of the Supreme Personality of Godhead is always thinking of how the fallen, conditioned souls can be delivered. The Supreme Personality of Godhead, influenced by the merciful devotees’ attempt to deliver fallen souls, enlightens the people in general from within by His causeless mercy.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 4.29.46, Purport

Speaking hari-katha [topics about Krishna] is real rest – it removes all fatigue. . . . Exalted personalities and their followers always engage in glorifying topics about Hari in all respects. They have no other duty. Chaitanyadeva also instructed us, kirtaniyah sada harih: always chant the glories of Hari. The symptom of liberated persons is that they only chant the glories of Hari at all times with body, mind, and speech.
Srila Bhaktisiddhanta Sarasvati Thakura
Uncommon Dialogues, Conversation 5

The jiva [living entity] is part and parcel of cid-vastu, the absolute transcendence; hence, he possesses the same qualities as the Absolute Whole, but in minute measure. . . . Free will is certainly present in the nature of the jiva, but proportionate to his infinitesimal size. The intrinsic constitutional presence of free will has elevated the jiva to a much higher status than matter and has made him its lord and master in the material sense. It has also favored him with the possibility of becoming the dearmost servitor of the Supreme Lord.
Srila Bhaktivinoda Thakura
Jaiva Dharma, Chapter 16

As a blind person cannot see anything, even with the help of a lamp or a mirror, persons who are averse to Lord Vishnu cannot see Him even if He stands before them.
Padma Purana, Uttara-khanda

The soul’s designation, the mind, is the cause of all tribulations in the material world. As long as this fact is unknown to the conditioned living entity, he has to accept the miserable condition of the material body and wander within this universe in different positions. Because the mind is affected by disease, lamentation, illusion, attachment, greed, and enmity, it creates bondage and a false sense of intimacy within this material world.
Jada Bharata
Srimad-Bhagavatam 5.11.16

What is the value of religiosity, economic development, and sense gratification to one who has firm devotion for You, the Personality of Godhead, the root of all the worlds? Liberation sits in the palm of his hand.
Sri Vishnu Purana 1.20.27

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.
