A person in ignorance of the principles of religion who therefore does nothing in the matter of religion is far better than a person who misguides others in the name of religion without reference to the factual religious principles of devotional service. Such so-called leaders of religion are sure to be condemned by Brahma and other great authorities.
His Divine Grace A. C. Bhaktivedanta Swami Prabhupada
Srimad-Bhagavatam 3.9.10, Purport

The vibration of My transcendental flute attracts the three worlds, but My ears are enchanted by the sweet words of Srimati Radharani.
Lord Sri Krishna
Sri Chaitanya-charitamrita, Adi-lila 4.244

The conditioned soul cannot revive his Krishna consciousness by his own effort. But out of causeless mercy, Lord Krishna compiled the Vedic literature and its supplements, the Puranas.
Sri Chaitanya Mahaprabhu
Sri Chaitanya-charitamrita, Madhya-lila 20.122

I offer my obeisances to Him of spotless fame, the Supreme Lord Krishna, who manifests His all-attractive personal expansions so that all living beings can achieve liberation.
Narada Muni
Srimad-Bhagavatam 10.87.46

The material desire to enjoy the material world and the desire to become liberated from material bondage are considered to be two witches, and they haunt one like ghosts. As long as these witches remain within the heart, how can one feel transcendental bliss? As long as these two witches remain in the heart, there is no possibility of enjoying the transcendental bliss of devotional service.
Srila Rupa Goswami
Bhakti-rasamrita-sindhu 1.2.22

Those who are eager to awaken their spiritual consciousness and who thus have unflinching, undeviated intelligence certainly attain the desired goal of life very soon.
Naradiya Purana
Quoted in Bhakti-rasamrita-sindhu 1.2.103

All the creative energies, which are inconceivable to a common man, exist in the Supreme Absolute Truth. These inconceivable energies act in the process of creation, maintenance, and annihilation. O chief of the ascetics, just as there are two energies possessed by fire—namely heat and light—these inconceivable creative energies are the natural characteristics of the Absolute Truth.
Vishnu Purana 1.3.2
