We are One-and as such-we all hold parts or pieces that may help another remember who they are or help clarify things that they do not understand. Sometimes one friend holds the space that is needed for one specific event where the other friend may not, yet all these people in our life play a role in our development. In certain events it is like unlocking a code to something we needed to hear/know in order to heal aspects of ourselves. Our body then literally becomes unlocked with this new information and healing may occur.
Research by Dr. Masaru Emoto shows how the vibration of water changes depending on the word that is spoken into it-as such-so is our body. Certain words will trigger an emotion that will then ripple throughout our body and cause a change.
