Why be unhappy about something if it can be remedied? And what is the use of being unhappy about something if it cannot be remedied?
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?
ShantidevaMay I become at all times, both now and forever: a protector for those without protection; a guide for those who have lost their way; a ship for those with oceans to cross; a bridge for those with rivers to cross; a sanctuary for those in danger; a lamp for those without light; a place of refuge for those who lack shelter; and a servant to all in need.
Shantideva
