Маджхима Никая 4:105
SUJATOYañhissa, bhikkhave, avinodayato uppajjeyyuṁ āsavā vighātapariḷāhā, vinodayato evaṁsa te āsavā vighātapariḷāhā na honti.
For the distressing and feverish defilements that might arise in someone who lives without dispelling these things do not arise when they are dispelled.
