 So, as we can see the dependent and the imaginary natures together explain the Yogācāra’s conventional reality and the perfect nature explains its conception of the ultimate reality. The first two natures provide an argument for the Yogācāra’s empirical and practical standpoints (vyavahāra), conventional truth and the third nature an argument for its ultimate truth. Even then the dependent nature alone is conventionally real and the perfect nature alone is ultimately real. By contrast, the imaginary nature is unreal and false even by the empirical and practical standards. This is true in spite of the fact the imaginary nature is constitutive of the conventional truth.
