In the mishnah that opens the second chapter of Avot, Rabbi Yehudah HaNasi asks:
Which is the derech yasharah (the "right path") for a person to choose?
He answers his own question thus:
Whatever is a tiferet for the one who does it, and a tiferet for one's fellow humans.
The word "tiferet" cannot be easily translated into English. Suggestions in published translations include that which is glorious, harmonious, creditable and so forth. However, this is only a description of the path a person should choose, not an indication of what that path actually is.
