From instructions by Saint John Vianney, today’s patron saint:
Prayer is nothing else but union with God. When one has a heart that is pure and united with God, he is given a kind of serenity and sweetness that makes him ecstatic, a light that surrounds him with marvelous brightness. In this intimate union, God and the soul are fused together like two bits of wax that no one can ever pull apart. This union of God with a tiny creature is a lovely thing. It is a happiness beyond understanding.
