The six kinds of defiled mind taught in the Awakening of Faith 起信论. Although the essence of the mind is originally pure， ignorance arises based on non-enlightenment， and the mind becomes tainted by defilement， which can be seen in six aspects: defilement associated with attachment 执相应染， defilement associated with non-interruption 不断相应染， defilement associated with discriminating wisdom 分别智相应染， defilement not associated with manifest form 现色不相应， defilement not associated with the mind of subject views 能见心不相应染 and defilement not associated with fundamental karma 根本业不相应染.［大乘起信论、 T 1666.32.577c］The first two of these are associated with the first six consciousnesses 六识， the third is associated with the seventh consciousness 第七识 and the final three with the eighth consciousness 第八识. ［二障义HPC 1.795a］
