Abstract
Mindfulness is examined using the Abhidhamma system of classification of phenomena (dharmas) as found in the Pali work Abhidhammattha-saṅgaha. In this model the mental factors constituting the aggregate of formations (saṅkhāra) are grouped so as to describe a layered approach to the practice of mental development. Thus all mental states involve a certain set of mental factors, while others are added as the training of the mind takes place. Both unwholesome and wholesome configurations also occur, and mindfulness turns out to be a rather advanced state of wholesome constructed experience. Wisdom, the prime transformative factor in Buddhist thought and practice, arises only under special conditions. This system is then contrasted with the different parsing of phenomena presented in the Sanskrit Abhidharmakośa, where both mindfulness and wisdom are counted among the universal factors, which provides a basis for an innatist model of development; this is then critiqued from a constructivist perspective.
