心如深海天然冷心如蓝天天然蓝
[xīn rú shēn hăi tiān rán lĕng xīn rú lán tiān tiān rán lán]
Translating as 'the heart, just like deep sea, is naturally cold; the heart, just like sky, is naturally blue'. This reflects a philosophical mindset or inner peace. It conveys indifference, aloofness and at the same time vast openness of spirit—like wide seas and open skies.
