All the happiness there is in this world Arises from wishing others to be happy. And all the suffering there is in this world Arises from wishing oneself to be happy.
ShantidevaThose desiring to escape from suffering hasten right toward suffering. With the very desire for happiness, out of delusion they destroy their own happiness as if it were an enemy
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.
ShantidevaWhatever happens, I will not let my cheerfulness be disturbed. Being unhappy won't get me anywhere and will dissipate all my goodness. Why be unhappy about something if you can change it? And if you can't, how will being unhappy help?
Shantideva
