Nakamura defines this term simply as "possessing defilement，" but in its usage in the Ratnagotravibha^ga， it indicates a subtle remainder of habit energy， the removal of which is beyond the scope of the practices of the two vehicles， and thus can only be dealt with by bodhisattvas. （sa^n%gana） Used in contrast to 有垢. ［宝性论T 1611.31.823b］
