My dear Captain Faiz,
Respectfully, the central theme of the words of profound wisdom you quoted was different: "Darkness makes Light much more appreciable."
Mirza Ghalib put it beautifully, though a difficult she'r for the common man:
LATAAFAT BAY KASAAFAT JALWA PAIDA KAR NAHIN SAKTI
CHAMAN ZANGAAR HAI AAIYNA-E BAAD-E-BAHAARI KI
(Beauty cannot glitter without ugliness (compared). A meadow is the rusty polish of the mirror of spring breeze.)
"Yeh ummat rivayaat meon kho gai
Haqeeqat khurafat mein kho gai"
Haqeeqat khurafat mein kho gai
Yeh ummat rivayaat mein kho gai
Thanks a lot!
