Faith means unflinching trust in something sublime. When one is engaged in the duties of Kṛṣṇa consciousness, he need not act in relationship to the material world with obligations to family traditions, humanity, or nationality. Fruitive activities are the engagements of one's reactions from past good or bad deeds. When one is awake in Kṛṣṇa consciousness, he need no longer endeavor for good results in his activities. When one is situated in Kṛṣṇa consciousness, all activities are on the absolute plane, for they are no longer subject to dualities like good and bad.
(Bhagavad-Gita----2:41----purport).

The mind is the original cause of material bondage. It is followed by many enemies, such as anger, pride, greed, lamentation, illusion and fear. The best way to control the mind is to engage it always in Kṛṣṇa consciousness (sa vai manaḥ kṛṣṇa-padāravindayoḥ (S.B.9:4:18). Since the followers of the mind bring about material bondage, we should be very careful not to trust the mind.
(Srimad Bhagavatam----5:6:5----purport).

Those sinful persons who are ignorant of actual religious principles, yet consider themselves to be completely pious, without compunction commit violence against innocent animals who are fully trusting in them. In their next lives, such sinful persons will be eaten by the same creatures they have killed in this world.
(Srimad Bhagavatam----11:5:14----translation).

The Supreme Personality of Godhead said: Nonviolence, truthfulness, not coveting or stealing the property of others, detachment, humility, freedom from possessiveness, trust in the principles of religion, celibacy, silence, steadiness, forgiveness and fearlessness are the twelve primary disciplinary principles. Internal cleanliness, external cleanliness, chanting the holy names of the Lord, austerity, sacrifice, faith, hospitality, worship of Me, visiting holy places, acting and desiring only for the supreme interest, satisfaction, and service to the spiritual master are the twelve elements of regular prescribed duties. These twenty-four elements bestow all desired benedictions upon those persons who devotedly cultivate them.
(Srimad Bhagavatam----11:9:33-35----translation).

Even though a woman be made of wood or stone, she becomes attractive when decorated. One becomes sexually agitated even by touching the form. Therefore one should not trust his mind, which is so fickle that it can give way to enemies at any moment. The mind is always accompanied by six enemies—namely, kāma, krodha, mada, moha, mātsarya and bhaya—that is, lust, anger, intoxication, illusion, envy and fear. Although the mind may be merged in spiritual consciousness, one should always be very careful in dealing with it, just as one is careful in dealing with a snake.
(Sri Caitanya Caritamrta----2:11:10----purport).
