To explain:
Ornaments placed on an old woman do not lose her beauty.
To explain: ornaments placed on an old woman do not produce beauty for her; on the contrary, their own charm is lost when they are placed on her.
Likewise, when poetic ornaments are placed in poetry devoid of qualities, there is an absence of their being the cause of poetic beauty and there is a loss of their own beauty.
As Bhaṭṭa Vāmana said:
“Poetry, like the beauty of a young woman, my friend, is relished when it possesses pure qualities; yet it is relished exceedingly / when affection is bestowed on it through continuous creations of genuine varieties of ornaments.
