There is light at your core. It is your connection to God, Goodness, to your Eternal Source, Life. You can feel this in your heart; it is often described as peaceful, calm, blissful, safe, and joyful, to name a few.
To be peaceful, you can connect to this light in your heartcenter. It just takes a breath, a thoughtful breath. With the intention of going directly to your heartcenter, breathe in deeply allowing your lungs to fully inflate around your heart. Following your breath occupies your mind and takes your attention right to the life-producing center of your body. This is where your eternal light shines.
It is a place of peace on earth. Come here often.
