Brtruhari’s Vairagyashatakam describes that everything in this world is coupled with fear: if we have wealth, we are fearful of thieves or taxman; if we have physical beauty, we are afraid of old age; if we enjoy / over eat or drink then we are fearful of disease; if we are well learned then we are fearful of learned opponents who can bring us down.....the only thing that would make us fearless is vairagya - not clinging to enjoyments / not being psychologically dependent on any object, person, situation, circumstance for our happiness.
