Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? 1 Corinthians 3:16 KJV
To be aware is to beware.
When you are aware of the holy, awesome presence of the Spirit of God abiding within you, you will beware of entertaining or touching any unclean thing.
His presence is too precious to ignore, too meaningful to minimize, to delightful to disregard, and too pure to polute.
As it is written: “Be ye holy as I Am holy.”
