'The five branches of heedfulness': vigor in the three times constitutes three; holding and arousing the prior expedients of diligent application across the three times, giving rise to extremely distinguished prior activities, with applied preparation and attention, is the fourth; because that attention and vigor are co-existent, all minds, mental factors, and bodily and verbal karmas proceeding simultaneously constitute the fifth branch.
