Sorrow is a necessary step to healing. You need not stay in that state, but it does help to recognize it. What comes next is up to you. It is you who transmutes the lower energy and raises it to a more comfortable place. There are no timelines for overcoming grief and loss. It is a process of learning and adjusting, and then deciding what is the best way to live in the present moment.
All of life is about change. When things change, there is loss. Nothing lasts forever, but the soul. When you can come to terms with this fact and not hold on so dearly to the past, you can flood your present with healing love and compassion for all others. All suffer loss. All need love. No one bypasses the route to the soul. Flood your world with love and help to ease the suffering.
