"The modest Rose puts forth a thorn, The humble sheep a threat’ning horn: While the Lily white shall in love delight, Nor a thorn nor a threat stain her beauty bright."
The Rose, symbolic of love, is a two-edged sword. Love is at once the purist gift, the highest attainment, and yet the source of the deepest of wounds. Love's innocence, betrayed, breeds self-protective thorns which inevitably lead to disaster, as the purity of love itself is stained by its need to protect itself. It falls from grace, one might say, and becomes, thereby, by experience, modest.
The sheep is the matured lamb, the experienced and thus now altered version of the innocent lamb who reminds us whom we ourselves reflect when we reside in our true nature, the source of infinite love itself.
A Lily is historically and religiously a symbol of purity. Only by a connection to inner purity, may one delight in love and beauty. Purity deserves these delights; thorn and threat by their very nature forfeit them.
(The Rose is made modest, the sheep humbled.... Only the Lily, forever pure, rises above in glory.)
