3 KudoZ points awarded for this answer. Comment: "As before, I would like to thank everyone for their useful input, but am awarding Akio for both her research and analysis. Unlike Akio, I am unable to access the perikansha.com domain from my location in Korea and greatly appreciate her having been able to explore this avenue on my behalf. My own analysis and conclusion are based on the information provided by Akio and others: 1)) On the one hand, the term 地平 appears to be an abbreviation for 地平線 which, in turn, can be substituted with the term 水平線 (horizon). On the other hand, the term 地平 appears to be a term in its own right and has to do with the undulating shape of the earth's surface -- namely, the contours (landscape) of the earth's surface. 2) The term 水脈 can refer to underwater currents (みお), as well as, underground water currents (すいみゃく). In addition, it can also refer to the paths that ships follow or leave on the water's surface. What all of these terms share in common is movement along a path. 3) Although the term undercurrents matches well the substance of the Kawashima article of my previous post on 被占領心理, the book in which the article is apparently contained appears to be much broader in scope. Thus, I am not at all convinced that the juxtaposition of word pairs like visible and invisible, and above and below are appropriate in this context. 4) The term 思想 does not appear to be very problematic, as the two characters are nearly synonymous in meaning. In fact, one can write 思う and 想うto indicate the same notion -- namely, おもう. In short, the debate between thought, ideology, and mindset may or may not be important. Unfortunately, I cannot know without a copy of the book in front of me. Finally, the title that I have chosen is literary, neutral, and in keeping with the vocabulary of the editor's Japanese title.
