 To accomplish this, according to the account given in Tiantai texts, we must first apprehend the instant of experience itself as a single whole. That means to see all the elements of this moment’s experience as mental experience, but specifically as a single mental experience, in which all these elements are simultaneously present, related to one another in a specific instantaneous structure. This requires some training in attentiveness to all elements of a single moment equally; the normally neglected aspects of a single moment’s experience, its peripheral or indistinct elements, are laid out in the above enumeration of every possible state one can think of, as a way of trying to reach into every nook and cranny of what one means by “everything that I can think of right now.” This includes both the knower and the known, as well as whatever way the division between them presents itself. For although the knower is not present in the same way other objects of experience are, its presence is felt in some form; whatever is apprehensible as the presence of the agent of this mentation, the activity that separates itself off from the objective contents, the knower as opposed to the known, as well as the act of opposition itself, is also to be included as an aspect or part of the world as I know it and imagine it. Also to be included is the imagined as well as the perceived, the possible as well as the actual. Also included must be the moment’s sense of its own transitoriness, the sense of being situated between a gone past and yet to come future, however these may manifest in the experience. All elements perceived or conceived are to be taken in and noted. The next step will be to apprehend these all as felt aspects of a single mental event, a single entity with all these many characteristics in their specific relations of this moment appearing at once, and all disappearing at once, such that not one can be changed or replaced. It must be experienced as a specific total structure of just these elements, in just these relations, and none other.
