When you apply this simple precept alone, you will have travelled at least fifty percent of the way towards happiness.
Look at farmers, carpenters, bakers and observe how, when they are working they recite words as melodious as the singing of the birds because they are content.
Afterwards observe yourself and how you toss and turn on your bed while wiping away your tears, always miserable, always torturing yourself…
(‘Aaidh ibn Abdullah al-Qarni)
