青丝成雪亦常伴君侧一掷千金为许卿长欢
[qīng sī chéng xuĕ yì cháng bàn jūn cè yī zhì qiān jīn wéi xŭ qīng zhăng huān]
Roughly translated as 'Turn gray and stay beside you for eternity, willing to squander riches for your eternal joy,' reflects a commitment to love someone unconditionally, no matter what, expressing unwavering devotion, possibly toward a cherished person or muse.
