The word hari conveys various meanings, but the chief import of the word is that He (the Lord) vanquishes everything inauspicious and takes away the mind of the devotee by awarding pure transcendental love. By remembering the Lord in acute distress one can be free from all varieties of miseries and anxieties. Gradually the Lord vanquishes all obstacles on the path of devotional service of a pure devotee, and the result of nine devotional activities, such as hearing and chanting, becomes manifested.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 1.7.10, Purport

Though engaged in all kinds of activities, My pure devotee, under My protection, reaches the eternal and imperishable abode by My grace.
Lord Sri Krishna
Bhagavad-gita 18.56

To taste the fruit of devotional service in Goloka Vrindavan is the highest perfection of life, and in the presence of such perfection, the four material perfections—religion, economic development, sense gratification, and liberation—are very insignificant achievements.
Sri Chaitanya Mahaprabhu
Sri Chaitanya-charitamrita, Madhya 19.164

Who can be worthy of the name of the Supreme Lord but the Personality of Godhead Sri Krishna? Brahmaji collected the water emanating from the nails of His feet in order to award it to Lord Shiva as a worshipful welcome. This very water [the Ganges] is purifying the whole universe, including Lord Shiva.
Shukadeva Goswami
Srimad-Bhagavatam 1.18.21

Give up the company of evil persons, partake of the association of saintly persons, perform pious deeds both day and night, and remember always the flickering nature of the material world.
Chanakya Pandita

Deluded by ignorance, bewildered souls think themselves steady and wise. Baffled by their own conceit, they set themselves up as scholars and thus lead other ignorant souls further into darkness. In this way, those blinded by ignorance lead similarly blind men into the darkness of oblivion.
Katha Upanishad 1.2.5

Lord Krishna, the cowherd, transcends not only the material consciousness of wakefulness, dream, and deep sleep, but also the fourth realm of pure, spiritual awareness.
Gopala-tapani Upanishad (Uttara 96)

The infinite world of spiritual bliss is called Vaikuntha. There the Supreme Truth lives, being glorified by the personified Vedas, who are also present there.
Brihad-vamana Purana

As a web is expanded and withdrawn by a spider, as plants grow from the earth, and as hair grows from a living person’s head and body, so this universe is generated from the inexhaustible Supreme.
Mundaka Upanishad 1.1.7
