Initially, prajñā is attained at a conceptual level by means of listening to sermons (dharma talks), reading, studying, and sometimes reciting Buddhist texts and engaging in discourse. Once the conceptual understanding is attained, it is applied to daily life so that each Buddhist can verify the truth of the Buddha's teaching at a practical level. Notably, one could in theory attain Nirvana at any point of practice, whether deep in meditation, listening to a sermon, conducting the business of one's daily life, or any other activity.
