It is a beautiful haiku!
However, meigetsu (名月 or 明月) means a representative season term for autumn.
Though the translation of full moon is mangetsu(満月), this is a season word of autumn, too. You can watch the full moon in winter, but this is a rule in haiku.

If you want to strike your opponent, you should let him strike at you.
If your opponent strikes at you, he himself will already have been struck.
