The way to begin to spiritualize one’s life is through meditation and contemplation.
Think about it. What you think about you bring about; to an extent. Certainly, when you are thinking of God, in a silent environment you are aligning yourself with His energy.
Silence is the sound of God in creation. This is why when meditating it is best to have no distractions. To be in silence or to have prayers or mantras of Gods name in the background. It aligns you into His realm.
This is a Law of God. When you are able to be in His energy, this silence is His reflection of Peace. As you practice this silence and alignment regularly, after a while you walk with it, it becomes a part of you and you reflect it outward into the world.
Thus changing the world by changing ourselves.
