It is not possible to control all external events; But, if I simply control my mind what need is there to control other things?
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.
ShantidevaAll the harm, fear, and suffering in the world are caused by attachment to the self: Why should I hold on to this great demon?
