Chapter Five begins with the Bodhisattva Paramārthasamudgata, who asks what the Buddha's "implicit intent" is when he taught two kinds of doctrine: doctrines which explain reality by describing it analytically (such as through the schemas of dependent origination, the four noble truths, and the realms of existence), and also those doctrines which state that "all things have no-essence, no arising, no passing away, are originally quiescent, and are essentially in cessation." In answering this question, the Buddha applies his schema of the three natures to understand the nature of absence of essence. The Buddha states there are three ways in which things are said to have no essence: I have explained that all things whatsoever have no-essence, for descriptive marks have no-essence, arising has no-essence, and ultimate meaning has no-essence. Good son, descriptive marks have no-essence, for all things are characterized by imaginative clinging. This is so because it is names and symbols that establish those marks, and there is no inherent characteristic in things. This then is what I call the no-essence of marks. The arising of things has no-essence, for all things arise in dependence upon others. This is so because they depend upon the causal power of others and do not arise from themselves. Therefore this is what I call the no-essence of arising. The ultimate truth of all things has no-essence, for, from their arising, all things have no-essence. This is what I call the no-essence that is identical with the conditioned arising of things. I also call it the no-essence of ultimate meaning because I preach that among all things, that realm of the purified content of understanding is to be regarded as the no-essence of ultimate meaning. Thus, these "three no-essences" are said to correspond to the three natures:
