If you conceive of the Buddha in terms of the characteristics of purity, brilliance, and liberation, and if you conceive of sentient beings in terms of the characteristics of impurity, darkness, and samsara—if your understanding is such as this, then you will never attain bodhi even after passing through eons [of religious practice] as numerous as the sands of the Ganges River. This is because you are attached to characteristics. There is only this One Mind and not the least bit of dharma that can be attained.
