These words were given to me to use at a "Remembrance Service" that I organized at the end of my residency days. This Remembrance was a service to remember the patients and family members lost by the Resident Physician-in-Training. These words from the Tibetan Book of Living and Dying were found by a friend, studying Buddhism.  
I found these words describe the essence of what I try to share with my patients. Re-reading them, these words serve as a "reality check" for me, when I question my reasons for being inthe medical field.  
Some of those reasons have become more evident, as people find this website and are helped. I still need daily reminder of why I became a doctor..."May I be the doctor, the medicine and may I be the nurse for all the sick beings in the world, until everyone is healed." 

May I be a protector to those without protection  
A leader for those who journey  
And a boat, a bridge, a passage  
For those desiring the further shore.  

May the pain of every living creature  
Be completely cleared away  
May I be the doctor, the medicine  
And may I be the nurse  
For all the sick beings in the world  
Until everyone is healed.  

Just like space  
And the great elements such as earth,  
May I always support the life  
Of all boundless creatures.  

And until they pass away from pain  
May I also be a source of life  
For all the realms of varied beings  
That reach unto the ends of space.
