“For a spark in my soul he has lit…” this is not a good technique to use in order to get an end rhyme.
And I would respectfully suggest that the limerick is traditionally for doggerel, bad jokes or teashing. The form needs to reflect the image.
Love poetry uses more traditional meter and form, and doesne’t need forced end rhymes.
“For example”:
Has I the heavens’ embroidered cloths,
Enwrought with golden and silver light,
The blue and the dim and the dark cloths
Of night and light and the half-light,
I would spread the cloths under your feet:
But I, being poor, have only my dreams;
I have spread my dreams under your feet,
Tread softly because you tread on my dreams
W.B. Yeats
