Allow yourself to feel all of your feelings, even the ones you may have been avoiding; the ones you may not want to feel.
Open your heart and be willing to feel and experience everything, including any emotions and other energies that your ego and mind may not want to feel.
Such emotions and other energies are often repressed and trapped in your subconscious and physical body, where they are stored as physical tension and blocks or heaviness in your energy field. If they are present, they can cause you to experience all kinds of maladies, physical and spiritual.
By allowing yourself to feel everything, you allow trapped energies to rise into your conscious awareness, where you can then give them the Love that they need, and allow them to be fully healed, completed and released.
Love heals all, in every situation.
