One should do nothing other than what is directly or indirectly of benefit to living beings.
ShantidevaWhy be unhappy about something if it can be remedied? And what is the use of being unhappy about something if it cannot be remedied?
ShantidevaMay I be a light for those in need of light. May I be a bed for those in need of rest. May I be a servant for those in need of service, for all embodied beings.
Shantideva
