Masekhet Soferim, an eighth-century compilation of Jewish laws regarding the preparation of holy books and public reading, states (Chapter 10:7) that Kaddish may be recited only in the presence of a minyan (a quorum of at least 10 men in Orthodox Judaism or 10 adults in Reform and Conservative Judaism). While the traditional view is that "If kaddish is said in private, then by definition it is not kaddish," some alternatives have been suggested, including the Kaddish L'yachid ("Kaddish for an individual"), attributed to ninth-century Gaon Amram bar Sheshna, and the use of kavanah prayer, asking heavenly beings to join with the individual "to make a minyan of both Earth and heaven". In some Reform congregations, a minyan is not required for recitation of the Kaddish, but other Reform congregations disagree and believe that the Kaddish should be said publicly.
