gradual passage from potency to act in the substance itself, so a bodily thing is in continuous renewal
General Technical Meaning
Substantial motion is gradual passage from potentiality to actuality in the category of substance itself. Bodily substances are therefore intrinsically in continuous flux and renewal, rather than undergoing change only in accidents.
In ʿAllāmah Ṭabāṭabāʾī’s Works
In al-Manāmāt, substantial motion names the soul's intrinsic passage through ontological ranks toward the limit of possible existence; the text invokes this established doctrine rather than proving it here.
