At the same time in each of the mental impulsions [of the cognitive processes], is present the one-pointedness mental quality (ekaggatā cetasika), which is associated with wisdom. Therefore, this ekaggatā develops as an indriya, develops as a bala, develops as a bojjhanga and develops as a factor of the path. In the mundane sense this becomes mundane sense-sphere merit. Now this citta ekaggatā is ekaggatā samādhi that will help one to realize the four paths & fruits one day, and this becomes samādhi-sambojjhanga.
