Working with the Five Hinderances
"Numerous things can give rise to doubt; everyone has their own special list. If we frequently give inappropriate attention to them, that only increases and compounds doubt. Thus for example, a common topic of speculation for many people is what will happen in the future, but it’s easy to see how you can become overwhelmed with doubt, uncertainty and confusion about that." - Ajahn Thiradhammo (Working with the Five Hindrances)
