Love is a rose and life is rice. What does this sentence mean?

Love is beautiful and dangerous. Like a rose, it attracts others, but like a rose, it has sharp thorns and is full of heartbreak and deception. And life is like rice, it may be boring, but it is as essential as rice. Life is the way to extend life. Without life, it's like walking dead. Love is the ornament of life, which enriches it.
