One who takes shelter of the Supreme Lord has nothing to fear, even in the midst of the greatest calamity.

Bhagavad-gita As It Is 1.19, Purport
Krsna is the Supreme Personality of Godhead and the cause of all causes. He is the original creator, maintainer, and annihilator, of all universes. Whenever Lord Brahma and Lord Rudra are described as the creator and annihilator it is to be understood that they are empowered secondary agents under the instructions of Krsna, and therefore they are established as predominating deities of the modes of passion and ignorance.
Srila Bhaktisddhanta Sarasvati Thakura
Sri Caitanya-bhagavata, Madhya 1.149, Commentary
The highest devotion is attained by slow degrees by the method of constant endeavor for self-realization, with the help of scriptural evidence, theistic conduct, and perseverance in practice.
Lord Brahma
Sri Brahma-samhita 5.59
What good is lust when youth has fled? What good is a lake that has no water? Where are the relatives when wealth is gone? Where is samsara [repeated birth and death] when the Truth is known?
Adi Sankaracarya
Bhaja Govindam 10
Those who understand the principles of social interaction say that . . . friendship with a good man may be established simply by exchanging seven words with him or walking seven steps with him. Friendship with a very good man may be established in merely three words or steps. But saintly persons establish friendships at every step.
Sanaka KumaraNarada Purana 1.36.32.33
By performing the sacrifice of congregational chanting of the holy name, learned scholars in the age of Kali worship Lord Krsna, who is now non-blackish because of the great upsurge of the feelings of Urimati Radharani. He is the only worshipable deity for the paramahamsas, who have attained the highest stage of the fourth order (sannyasa). May that Supreme Personality of Godhead, Lord Caitanya, show us His great causeless mercy.
Srila Rupa Gosvami
Stava-mala, Dvitiya Caitanyastaka 1
Who, other than one who is not a human being, can exist in this world and not be interested in the ultimate goal of life? Who can refuse the nectar of narrations about the Personality of Godhead's activities, which by itself can deliver one from all material pangs?
