Devotion is not simply the worship of the Lord; it is much more than that. Primarily, it is the control of the senses; for, when life is offered as worship, the senses do not run after transient things. They can be thus controlled, for man is not a weak animal; he is endowed with mighty spiritual power and he can learn to use it; he can tap this power through prayer, which brings down Grace to fill the reservoir of his heart. Man tames the lion and the elephant to obey his call; can he not tame his emotions and passions? Make your strength evident in the face of hardships; when all goes well, you become soft, the blows of defeat toughen you into heroes.
