 While the ONA has stated that it is not an occult organization in the conventional sense but an esoteric philosophy , several academics have written about ONA membership . In a 1995 overview of British Satanist groups , Harvey suggested that the ONA consisted of less than ten members , " and perhaps fewer than five . " In 1998 , Jeffrey Kaplan and Leonard Weinberg stated that the ONA 's membership was " <unk> small " , with the group acting primarily as a " mail @-@ order ministry " . Regarding the question of membership , Anton Long , in a letter to Aquino dated October 1990 , wrote that " once the techniques and the essence [ of the ONA ] are more widely available then membership as such is irrelevant , since everything is available and accessible ... with the individual taking responsibility for their own development , their own experiences .
