Look not back. No, not even if you see the dearest and nearest cry. Look not back, but forward. We cannot stop. If we stop we die. We have either to go forward or to go backward. We have either to progress or to degenerate.
Swami VivekanandaSeek ye first the kingdom of God, and everything shall be added unto you. This is the one great duty, this is renunciation. Live for an ideal, and leave no place in the mind for anything else. Let us put forth all our energies to acquire that which never fails-our spiritual perfection. If we have true yearning for realization, we must struggle, and through struggle growth will come. We shall make mistakes, but they may be angels unawares.
Swami VivekanandaDo not be afraid of a small beginning. great things come afterwards. Be courageous. Do not try to lead your brethren, but serve them. The brutal mania for leading has sunk many a great ships in the waters of life. Take care especially of that, i.e. be unselfish even unto death, and work.
Swami Vivekananda
