Wow! You're asking some interesting and important questions here. And you've done some impressive research into all those different languages. In Arabic, nafs is also used in the sense of soul, psyche, essence, individual, essential truth, mind, one's own opinion... and the verb formed from the same root (tanafas, 5th tribe) means to breathe, sigh. From the root ruh we also have the word riha, which means scent, aroma (things you breathe in)
