Brihad Bhagavatamrta
Part 1 Chapter 7 Text 98

tamisra-punjadi yad eva kincin
madiya-varnopamam iksyate taih
sa-cumbanam tat parirabhyate mad-
dhiya param ta kva nu varnaniyam

TRANSLATION
If they see a patch of darkness resembling My complexion, they embrace and kiss it, mistaking it for Me. What more can I describe?
