Trusting a message that comes from seemingly nowhere, from an unseen, intangible source, may feel risky to you and you are not alone in your feelings.
When we witness something physical, we typically believe it more. You look into the eyes of your loved one, feel their warm embrace and hear them say, "I love you." You don't think for a moment it's not real or doubt the reality that it happened. But we doubt spirit.
We've been conditioned to trust our physical senses and doubt our nonphysical senses. It started at a very early age.
What if you gave as much validation to your nonphysical senses as you did to your physical ones? Then, when you receive an insight of how your spirit guide may appear, feel the sense of their presence and hear a thought come into your mind of something helpful, you will know that what happened is as real as your friend giving you a hug.
