Yardena obtained various Aryan documents, mainly by using the Population Registry offices. She visited the offices pretending to look for fictitious names and from the list she was given she wrote down names of real Aryans. Later, a member of the movement (in most cases, a young woman) came into the office and asked for a copy of an authentic document, bearing one of the names taken from the list.
Yardena fled to Romania. From there she made aliya.
