Jayyāsh is an emphatic descriptor of welling or surging energy, connected to j-y-sh (ج ي ش). Jāsha suggests rising or boiling up. Ḥamy relates to heat or fierce intensity; mirjal is a large cooking vessel or cauldron.
Ihtizām conveys forceful stirring, disturbance, or vibration. Kaʾanna introduces the comparison and ghalyu mirjal supplies its vivid counterpart. An otherwise abstract description of stamina becomes a visible, boiling image.
Ḥamyuhu should not be confined to human anger: here it represents energetic heat and excitement. The pairing is a spare physique with exceptional vigor.
