The kinds of disordered digestive fire

Disordered digestive fire is of three kinds caused by the doshas: irregular (viṣama) from vāta, sharp (tīkṣṇa) from pitta and weak (manda) from kapha. Footnotes define them: irregular fire sometimes digests a proper meal and sometimes not, sharp fire digests even an excessive meal, and weak fire cannot digest even a small one.
