Maybe ,Yeah you'r right, his pose looks like vow of silence..Thanks for noticing me.Not only his album, but also You will find his all songs like Satanism..I was big fan of this boy, but day by day I understood that Jackson is a literally problematic guy..When I listened his first solo song , I felt like WTF!!..It was super weird..I don't know truth of this information , I got , But some fans from Hongkong said that His hometown people don't like his family (his family is popular) and His teachers literally hated him for his nasty behavior..Hi, I do not know about that statue, but maybe his pose looks like the vow of silence? And also because you mentioned him, I have just looked up his Instagram, he has some pictures where there is a red string on his hand, I think he is part of Kabbalah (Jewish mysticism, often practised by the Illuminati). And his album cover is a hexagon with a dot in the middle, looks like Sun-worshipping symbol (Luciferic).
This is just my opinion, maybe the others would have better answers.
