Another condition of the true quantity is that it must be free from confusion, that is, the sensory organs will not be disordered. For example, if the person suffering from blindness is visually disordered, or if the rotating fire is used as a wheel, the real quantity cannot be formed. Buddhist logicians believe that "no confusion" and "no difference" are indispensable and necessary conditions for the formation of true reality. If the senses are confused, even if you leave all the differences such as famous sayings and types, it is not true. On the other hand, if the famous sayings, categories and other ideological activities are added, even if the senses are not confused, they can't be regarded as true quantities. (Shen Jianying)
