"Petal nor thorn could save this rose."
From "Flowers...Beautiful Flowers"
This line personifies the loss of life and the harvest of flowers (roses) for a funeral. Just as loved ones are lost each day in the prime of life (any time really), the rose is taken in the height of beauty and placed atop the grave. This is in spite of the thorns which protect it. We possess the attributes of the rose as well. Yet, still we pass, regardless of benevolence or wickedness.
