Those hours, that with gentle work did frame
The lovely gaze where every eye doth dwell,
Will play the tyrants to the very same
And that unfair which fairly doth excel;
For never-resting time leads summer on
To hideous winter, and confounds him there;
Sap checked with frost, and lusty leaves quite gone,
Beauty o’er-snowed and bareness every where:
Then were not summer’s distillation left,
A liquid prisoner pent in walls of glass,
Beauty’s effect with beauty were bereft,
Nor it, nor no remembrance what it was:
But flowers distill’d, though they with winter meet,
Leese but their show; their substance still lives sweet.
In plain English
The same passing hours that gently shaped your beautiful face will eventually turn cruel and destroy that very beauty. Time is relentless — it pushes summer forward into a hideous winter, stripping away vitality and leaving only bareness behind.
If you didn't preserve your beauty somehow — like flowers distilled into perfume, captured and sealed away — beauty itself would simply vanish. Future generations would have no trace of what you were, no memory at all.
But here's the thing: flowers that are distilled into essence survive the winter. They lose their visible form, but their essential sweetness endures. So too, if you have children, your beauty lives on in them.
