Locus Classicus

Its April of 2019 and Day 12 of A to Z Challenge. I am doing Foreign word/phrase a day and 8 line poem for it.

Word/Phrase: locus classicus
Language: Latin
Meaning: the best known or most authoritative passage on a subject

Poem:
the fallen leaves,
the shady dust,
the weak stand,
the fragile cover,
the shoddy path,
the evil thoughts,
natures  locus classicus,
rain, said – wash away!

Interpretation:
The rain current can wash away a lot of things. Only a stronger foundation can sustain. The roots are to be grounded firm and strong. (Now that applies to a lot of things!)
