Lowell Lo–一生所爱

* Ocean of suffering (苦海): a word of Buddhistic origin (https://en.wiktionary.org/wiki/%E8%8B%A6%E6%B5%B7). Buddhism states that existence is characterized by continuous changes and reincarnations (Saṃsāra, https://en.wikipedia.org/wiki/Sa%E1%B9%83s%C4%81ra), and the sufferings in the process.

** World (世间): another word of Buddhistic origin (https://zh.wikipedia.org/wiki/%E4%B8%96%E9%96%93).

*** World (尘世): another word of Buddhistic influence (https://en.wiktionary.org/wiki/%E5%A1%B5%E4%B8%96). Literally it means "the world of dust", and figuratively it means "the world of mortals".

All three words have entered common use in Chinese (including Mandarin and Cantonese) and become part of everyday parlance, despite their Buddhistic origins.
