The holy names of Krishna are the bestowers of all spiritual benedictions and are non different from Krishna, the embodiment of all transcendental mellows. Simply by chanting the holy names of Krishna, one relishes the transcendental mellows related with Krishna. There is no possibility of relishing the transcendental mellows related with Krishna by any other process.- Srila Bhaktisiddhanta Sarasvati Thakura Sri Caitanya-bhagavata, adi-khanda 16.21, Commentary

The truth can never be lost; it can only be forgotten. The soul’s eternality and the existence of the Absolute Truth cannot be established by argument, because argument has no entrance into the realm beyond the material world. Self-realization is the only way to establish these truths.- Srila Bhaktivinoda Thakura, Sri Krishna-samhita 9.4, Commentary

The practical injection to stop all the fructifications of the seeds of our sinful activities is simply engagement in Krishna consciousness.- His Divine Grace A. C. Bhaktivedanta Swami Prabhupada, The Nectar of Devotion, Chapter One

A transcendentalist who does not completely control his words and mind by superior intelligence will find that his spiritual vows, austerities, and charity flow away just as water flows out of an unbaked clay pot.- Lord Sri Krishna, Srimad-Bhagavatam 11.16.43

If one is infected with the desire for material enjoyment or material liberation, he cannot rise to the platform of pure loving service unto the Lord, even though he may superficially render devotional service according to the routine regulative principles.- Sri Caitanya Mahaprabhu, Sri Caitanya-caritamrta, Madhya-lila 19.175

As a web is expanded and withdrawn by a spider, as plants grow from the earth, and as hair grows from a living person’s head and body, so this universe is generated from the inexhaustible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

At the end of the millennium the great Mount Meru may shake. At the time of partial devastation, the seven oceans may be disturbed. But the saintly persons, being resolute in purpose, are never disturbed. – Canakya Pandita

The six divisions of surrender are the acceptance of those things favorable to devotional service, the rejection of unfavorable things, the conviction that Krishna will give protection, the acceptance of the Lord as one’s guardian or master, full self-surrender, and humility.- Srila Sanatana Goswami, Hari-bhakti-vilasa
