What exactly are etheric cords? How would a cord cutting help my energy? As soon as you communicate or meet someone you form an etheric cord. These cords are essentially there for a lifetime. Cutting cords may be beneficial if you have a toxic history with a person and feel their energy is lingering throughout your life. Cutting the cord can help break the energetic attachments created and can help you to move on to receive new opportunities in your life. This practice is extremely common in the spiritual community and can bring a positive outcome if done right.
