Description

See source sheet. Just to add: This concept of the Rizhiner that the main Yichus is to be the father of Tzadikim comes from his great grandfather, the Magid of Mezritch. It is told that as a young boy, a fire destroyed his family's home. His mother was devastated since a book with the family Yichus was consumed in the fire. To console his mother he turned to her and said not to worry, that a new line of Yichus would begin with him. This is the 'Yichus' from which the Rizhiner comes from.
