Instead of worshiping Lord Visnu, people have been educated to worship matter. According to the direction of modern society, men think they can advance in civilization by manipulating matter to build skyscrapers, big roads, automobiles, and so on. Such a civilization must certainly be called materialistic because its people do not know the goal of life.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 5.1.14, Purport
In the teachings of Sriman Mahaprabhu, there are two principal instructions: developing a taste for the chanting of the Lord's holy names and displaying compassion for the fallen souls. The greatness of a Vaisnava depends on the extent to which he possesses these qualities. . . . All good qualities of a Vaisnava automatically manifest in a Vaisnava who endeavors for these two qualities.
Srila Bhaktivinoda Thakura
Sri Caitanya-siksamrta 1.7
And whoever, at the end of his life, quits his body remembering Me alone at once attains My nature. Of this there is no doubt.
Lord Sri Krsna,
One who sees that the living entities and the Supreme Lord are always distinct is very dear to the Lord.
(quoted by Srila Madhvacarya)
In Vaikuntha [the spiritual world] nothing exists but devotional service, rendered through sankirtana [collective glorification of the Lord] and in many other forms. It goes on incessantly, with great enthusiasm, spreading the ecstasy of pure love.
Sri Brhad-Bhagavatamrta 3.50
In Vaisnava philosophy there is no spirit of material enjoyment and there is no concept that material objects are enjoyable; rather than the attitude of enjoyment, the attitude of service is prominent.
Srila Bhaktisiddhanta Sarasvati Thakura
Sri Caitanya-bhagavata, Madhya 19.195, Commentary
A person who is not bewildered by the inevitable miseries of material existence, and who remains aloof from them by remembering the lotus feet of the Supreme Personality of Godhead, is to be considered a bhagavata-pradhana, the foremost devotee of the Lord.
Sri Havi rsi
For a person who is suffering in the fire of countless miseries and who desires to cross the insurmountable ocean of material existence, there is no suitable boat except that of cultivating devotion to the transcendental taste for the narrations of the Supreme Personality of Godhead's pastimes.
Srila Sukadeva Gosvami
