Inspired by Loyalty (Rokugan) (read this).
Loyalty is not the greatest virtue.
Virtue is neither described in an word, nor an action. It is something personal and yet altogether public. It is discovered within each of us individually and yet is something which is univerally available for persuit.
The greatest virtue is Love.
This is not the love of an ally, or friend, or of family, or a sibling, or that found in a relationship. This is love as a broad concept. The greatest virtue is the rightness of and in the purity, honesty and sincerity of Love.
It lets one stand proud and with inexhaustible warmpth as an inspiration to the world.
