You got to remember folks, Macross is first and foremost made for a Japanese audience. AFAIK, spirituality/mysticism is deeply rooted in Japanese society and psyche. A year ago, I had the fortunate experience to spend New Years in Kyoto. I went to a shrine that eve with a group of Japanese friends I made there. It was an amazing experience, nothing like how Western societies celebrate it. Love, music, spirita, magic, it doesn't surprise me Kawamori has/is using these elements.
