Edgerton favors the theory according to which poṣa/posa should be derived from puruṣa; however, the Tibetan translation reflects a different etymologization of the term that must have been current at the time of the Tibetan translations of Sanskrit texts. Pāli etymologies also suggest a link to the idea of “nourishing” (attabhāvassa posanato poso), and therefore we have preferred to follow traditional etymologies that better reflect how the South Asian and Tibetan masters understood the term.
