That's a new one to me. It's not in any of my books, and I even did a complex google search, and found no patterns with that term.
Perhaps it means a row of straight knitting or purling? (ie. a "rest" from the pattern) ???
If we could see a picture of it, and the instructions, we may be able to figure it out for you. Or you could try contacting the designer.

"There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep yourself open and aware to the urges that motivate you. Keep the channel open."
