What does Conoce bien cada guerra de la vida y del amor tambien mean?

Hard to translate this into English without losing its original meaning or sense, but It basically means that you should "know" every "battle in life" and every "battle of love" really well, it's quoted from a song and it makes a lot more sense in Spanish and in its original context:

conoce bien cada guerra, -know well every battle

cada herida, cada ser -every wound, every creature

conoce bien cada guerra de la vida, -know well every battle in life

y del amor también -and every battle of love as well.
