The key is always trusting yourself and believing in your intuition. In a world where we are taught that anything unseen is either "God" or your "imagination" we can easily discount what comes so naturally for us. If you are new to your healing practice I invite you to observe the patters that seem to always come up for you in your healing work with others. This can be a small pinch in your left arm which you later find is indicative of an ache that needs to be healed in your client's arm. Or it can be a figure that you can't see but know from a heart and soul level that this is a loving being that cares for your client which you understand later after several similar experiences that you are sensing your client's spirit guides and angels.
The level of impact healing others has on you is infinite. The universe has a great way of shinning a reflective mirror on us by the people we attract in our lives.
If you are a practicing healer or an aspiring healer I would love to hear your thoughts on this topic so feel free to drop a comment below :)
