This is an excerpt from a song I'm trying to translate:
自分とは何でどこへ向かうべきか
自分 - oneself,
何でどこ - why, where,
向かう - head (verb),
べき - suffix meaning "should"
My doubts are what とは means and what is the role of か in the sentence? I can't give the whole sentence a general meaning. Can you help me, please?
Thank you very much
