Ten immoral practices. These were found in the behavior of the monks of the Vajjiputtaka sect by Ya/sas， whose critique brought about the Second Buddhist Council. The ten kinds of behavior the Vajjis regarded to be pure are: （1） preserving salt in a horn 角盐净; （2） taking food when the shadow is beyond two fingers wide 二指净; （3） after finishing one meal， going to another town for another meal 他聚落净; （4） holding several confession ceremonies within the same monastic boundary 住处净; （5） confirming a monastic act in an incomplete assembly 随意净; （6） carrying out an act improperly and justifying it by its habitual performance in this way 所习净; （7） after eating， drinking unchurned milk that is somewhere between the states of milk and curd 生和合; （8） drinking unfermented wine 饮阇楼&FK-FB54;净; （9） using a mat without a border 无缘坐具净; and （10） accepting gold and silver 金银净.
