When you let someone look into your eyes while you are grieving, you share your grief with them and your grief is halved. When you share your joy, heart to heart and eye to eye, you joy is doubled.
When you let someone look you in the eye and you rest - you let them see the real you, the one you can't see nor know without being in relationship. Humans only work in relationship. We die alone.
When you let someone look into your eyes when you laugh the laughter of joy, you invite them into the room that holds your treasures and your future. Most couples do not share this intimacy with each other. Most people are not even aware of the room in their heart where their treasures are stored.
Remember, grief leads to joy and joy leads to strength. Sorrow leads to happiness which leads to slavery to events that generate happiness.
