'Habit energies.' Latent karmic impressions created from all of the words， thoughts， actions and external influences experienced by sentient beings， closely related to the concepts of "seeds" --i.e. karmic impressions which help to comprise the total character of the individual entity. Habit energies are distinguished from seeds by virtue of the fact that they are the traces that remain even after destroying the seeds existent in the a^laya-vijn~a^na. According to the Yoga^ca^ra school， the seeds and the habituated energies are removed during the period from the first bhu^mi until the tenth. These energies are fully eliminated only upon the attainment of Buddhahood， and therefore， as hindrances to liberation， are considered to be the most subtle， as all of the other hindrances proper of affliction and noesis can be eliminated at advanced bodhisattva stages. （Skt. va^sana^; Tib. bag chags） ［唯识三十颂、 T 1586.31.61a; 成唯识论、 T 1585.31.43a; 瑜伽论T 1579.30.305b5］（2） In his Ijangui， Wonhyo describes two kinds of habit energies: distinctive 别习气 and shared 反通习气. ［二障义HPC 1.793c］
