As a Buddhist, we have to follow Lord Buddha. To become enlightened as a Buddha, there are 3 paths. Either you can select believing everything related to Dhamma. This is called “ශ්රද්ධා ශාසනය”. Second path is to know all the rules and try your level best to live without breaking any of them. That is called “ශීල ශාසනය”. In addition, there is an additionl path in Buddhism. That is by analysiing everything, you can get enlightenment. This is called “ප්රඥා ශාසනය”.
Now we have to apply these theories to day-to-day things such as Education, Career, Love, Marriage etc.
