This entry is for the bó reading of 魄, a bound form (b.f.) that appears almost exclusively in the compound 落魄 (luòbó), meaning 'down and out' or 'disheartened'. The English gloss 'soul; vigor; spirit' actually matches the far more common pò reading (as in 魄力, 魂魄), not the bó reading. As a bound form, 魄 (bó) cannot stand alone and almost never appears outside of 落魄. Be careful not to confuse this with the pò pronunciation, which carries the soul/vigor meanings.
