O son of Prthà! He does not meet with downfall either here in this world or in the hereafter. Know for certain, O dear one, that one who treads the path of virtue never goes the way of evil ones.
(BG 6.40)
Why should you not try to hit the mark? We come wiser through failures. Time is infinite. Look at the wall. Did the wall ever tell a lie? It is always the wall. Man tells a lie—and becomes a god too.
— Swami Vivekananda (CW, 4:126-27)

Even if you happen to be the worst of sinners, you will surely go across all sin by the raft of divine knowledge.
(BG 4.36)
Let a man go down as low as possible; there must come a time when out of sheer desperation he will take an upward curve and will learn to have faith in himself. But it is better for us that we should know it from the very first. Why should we have all these bitter experiences in order to gain faith in ourselves? We can see that all the difference between man and man is owing to the existence of nonexistence of faith in himself. Faith in ourselves will do everything.
— Swami Vivekananda (CW, 2:301)

Even a confirmed sinner, if he worships Me with unwavering faith and devotion, must verily be considered as righteous; for he has indeed taken the right resolve.
(BG 9.30)
Why weepest thou, brother? There is neither death nor disease for thee. Why weepest thou, brother? There is neither misery nor misfortune for thee. Why weepest thou, brother? Neither change nor death was predicated of thee. Thou art Existence Absolute.
— Swami Vivekananda (CW, 5:275)

Soon will he become righteous and attain to lasting peace. No devotee of Mine will ever perish; you may swear to this effect, O Arjuna!
(BG 9.31)
Let us proclaim to every soul: Arise, awake, and stop not till the goal is reached. Arise, awake! Awake from this hypnotism of weakness. None is really weak; the soul is infinite, omnipotent, and omniscient. Stand up, assert yourself, proclaim the God within you, do not deny Him!
— Swami Vivekananda (CW, 3:193)
