In theological terms, we speak of the Holy Spirit as the ruah Yahweh, the breath of God, who was spirated, is spirating, and will spirate for all eternity. As believers, we know the Holy Spirit is present in all places and filling all things. He gives life to the world; to the sacraments of Baptism, Chrismation, and Orders; and to the very core of our being.
Thus, the most fundamentally contemplative thing we can do is breathe. Physically, we know breathing brings in more oxygen to our lungs and brains. Mentally, we know it calms us down. Spiritually, we know it draws us closer to the Spirit.
So take time to breathe, deeply. It saves us from ourselves. It helps us to pray. It sanctifies us in the presence of the living God.
