 The ONA 's core system is known as the " Seven Fold Way " or " Hebdomadry " , and is outlined in one of the Order 's primary texts , Naos . The sevenfold system is reflected in the group 's symbolic cosmology , the " Tree of Wyrd " , on which seven celestial bodies – the Moon , Venus , Mercury , the Sun , Mars , Jupiter , and Saturn – are located . The term wyrd was adopted from Old English , where it referred to fate or destiny . Monette identified this as a " hermetic system " , highlighting that the use of seven planetary bodies had been influenced by the Medieval Arabic texts Ghāyat al @-@ Ḥakīm and Shams I @-@ Maarif . The Seven Fold Way is also reflected in the group 's initiatory system , which has seven grades through which the member can gradually progress . Theses are : ( 1 ) Neophyte , ( 2 ) Initiate , ( 3 ) External Adept , ( 4 ) Internal Adept , ( 5 ) Master / Mistress , ( 6 ) Grand Master / Mousa and ( 7 ) Immortal . The group has revealed that very few of its members raise to the fifth and sixth degrees , and in a 1989 article the ONA stated that at that point there were only four individuals who had reached the stage of Master .
