Carry the peace of heaven with you and contemplate the wonderous mystery that is your soul.

"Peace does not dwell in outward things, but within the soul; we may  preserve it in the midst of the bitterest pain if our will remains firm  and submissive. Peace in this life springs from acquiescence to, not in  an exemption from, suffering."

"Peace is the simplicity of heart, serenity of mind, tranquility of soul, the bond of love."

"Go forth in peace, for you have followed the good road. Go forth without  fear, for he who created you has made you holy, has always protected  you, and loves you as a mother."

"Do not lose your inner peace for anything whatsoever, not even if your  whole world seems upset. If you find that you have wandered away from  the shelter of God, lead your heart back to Him quietly and simply."

"For until I am one with him I can never have true rest nor peace. I can  never know it until I am held so close to him that there is nothing in  between."

"While you are proclaiming peace with your lips, be careful to have it even more fully in your heart."

"We are not at peace with others because we are not at peace with  ourselves, and we are not at peace with ourselves because we are not at  peace with God."

"Be at peace with your own soul, then heaven and earth will be at peace with you."

"God wants nothing from you but the gift of a peaceful heart."

"Strive to preserve your heart in peace; let no event of this world disturb it."

"If you seek peace and tranquillity, you will certainly not find them so  long as you have a cause of disturbance and turmoil within yourself."

"In order to bring true peace back to my soul, the only way that there exists on the Earth is Confession, because Jesus awaits me with His immense heart."

"What peace can we hope to find elsewhere if we have none within us."

"Keep your heart in peace and let nothing trouble you, not even your  faults. You must humble yourself and amend them peacefully, without  being discouraged or cast down, for God’s dwelling is in peace."

"Live in the joy and the peace of the divine Majesty. Live lost in divine love. Live for divine love and of divine love."

" Christ will come to you offering His consolation, if you prepare a fit  dwelling for Him in your heart, whose beauty and glory, wherein He takes  delight, are all from within. His visits with the inward man are frequent, His communion sweet and full of consolation, His peace great,  and His intimacy wonderful indeed. Therefore, faithful soul, prepare  your heart for this Bridegroom that He may come and dwell within you."

"The more a person loves God, the more reason he has to hope in Him. This  hope produces in the Saints an unutterable peace, which they preserve  even in adversity, because as they love God, and know how beautiful He  is to those who love Him, they place all their confidence and find all  their repose in Him alone."

"The soul that loves God has its rest in God and in God alone. In all the  paths that men walk in in the world, they do not attain peace until  they draw nigh to hope in God."

"Let us run towards the goal which from the beginning has been handed  down to us, the goal which is peace; and let us fix our gaze on the  Creator of the whole universe, and cling to his splendid and superlative  gifts of peace."

"The first stage of this tranquility consists in silencing the lips when  the heart is excited. The second, in silencing the mind when the soul is  still excited. The goal is a perfect peacefulness even in the middle of  the raging storm."

"Perform faithfully what God requires of you each moment, and leave the thought of everything else to Him. I assure you that to live in this way will bring you great peace."

"If God is for us, what evil could possibly harm us? One can never insist enough on the necessity of quiet, meditative prayer – the real source of interior peace. The heart does not awaken to confidence until it  awakes in love."

"Be peaceful within yourself, and heaven and earth will be at peace with  you. Be diligent to enter into the treasury that is within you, and you  will see the treasury of Heaven: for these are one and the same, and  with one entry you will behold them both. The ladder of the Kingdom is  within you, hidden in your soul. Plunge deeply within yourself, away  from sin, and there you will find steps by which you will be able to  ascend."
