There are many 7 basic aspects that are known to be covered by the warriors of the old but the most generalised list would be as follow:
勇 Yuu -Courage 仁 Jin - Benevolence
名 Mei - Honour 誠 Sei -Sincerity
忠 Chuu - Loyalty 義 Gi - Justice
礼 Rei - Respect
In my opinion, the 7 aspects listed above are too over blown to be only be adopted by the warriors. In fact, most of the aspects are what makes one a better human rather than just warriors.
