The "diamond-like sama^dhi，" or "adamantine absorption." （vajra-upama-sama^dhi） A state of deep meditative trance where all of the most subtle defilements are destroyed， which is the final stage of bodhisattva practice. Also called "vajra-sama^dhi 金刚三昧." Maha^ya^na schools state that this is the highest meditative state attainable in Hi^naya^na--the highest attainment of the arhat. In Maha^ya^na it is considered to be the same as "equal enlightenment 等觉." In Yoga^ca^ra， this state of concentration occurs in the consummating stage of practice 究竟道. ［二障义HPC 1.805a7］
