The aloe plant is known for its healing properties. Break a leaf and the sap that oozes out does wonderful things to heal a burn. That same sap will cover over the broken place on the plant and allow it to heal.
What skill that you have developed for healing yourself have you applied to helping others to heal?
Occasionally I write poems to process/express my emotions. Sometimes I share these with others, and once someone told me that this sharing had helped her.
There have been times when I thought that I perceived a problem that a friend might be having. If it seemed similar to one that I had encountered, I try to gently comment on the similarity and hope that the friend will feel open enough to share his/her difficulty. I try not to up-scale MY problem solution but to let my friend know that I am willing to listen and perhaps be part of the healing that can take place.
I have had friends who wrote poems such as Martin mentions which helped someone else get through a rough time. Good idea.
