All apparent phenomena are nothing but delusion, and there is, moreover, no freedom from delusion to be achieved by dispelling delusion. Delusion is, by its own essence, completely pure and, hence, enlightened. All phenomena are, in this way, primordially, fully, and completely enlightened. Phenomena appearing as various attributes are, therefore, indeed the mandala of vajra body, speech, and mind. They are like the Buddhas of the three times, never transcending the essence of complete purity. Sentient beings and Buddhas are not differentiated in terms of their essence. Just like distinct causes and results appearing in a dream, they are nothing but perceptions of individual minds brought forth by the power of imputation.
