"In expressing this vision in ordinary language, it has been necessary to use familiar terms in new ways. For example, 'space', 'time', and 'knowledge' refer to a special range of insights and to subtle facets of appearance. Our ordinary space and time are familiar aspects of a more fundamental 'space' and 'time' that are in effect; these terms also refer to particular levels of 'space' and 'time' as being appreciated by a particular 'knowledge'--a 'knowledge' that 'encompasses' all aspects of experience. Although we ordinarily 'take up residence' within a certain level, the opportunity remains for us to explore others if we wish. Furthermore, the possibility of altogether transcending particular 'spaces', 'times', and restrictive 'knowledge' is presented by what may be called Great Space, Great Time, and Great Knowledge." (p. xxxii, TSK)
"This vision pivots around the terms Space, Time, Knowledge (and Being). The discussions related to each of these terms often find echoes in the ideas of various modern disciplines and theories. However, when such parallels occur to you, it might be helpful to reread and investigate the discussions and exercises all the more closely, in order to determine the differences (as well as the similarities) in insight, context, and application between the ideas presented here and those presented elsewhere. In this way, premature interpretations can be avoided, and this vision's more unique applications, values, and effects can be seen and applied." (p. xxxiii, TSK)
Following are links to descriptions and definitions of time, space, and knowledge at three levels of insight ("rereadings will . . . reveal three main levels of insight" (p. xxxiii, TSK)). All material is quoted from the six works (abbreviated TSK, LOK, KTS, VOK, DTS, and DOT) listed in the bibliography.
Here are some excerpts on the three-level structure presented above and the process of defining time, space, and knowledge:
Cultivating knowledge in this way, we need not develop precise definitions of the terms that we use: not even the terms 'time' and 'space' and 'knowledge'. Although this is our usual way of knowing, the quest for such clarity can actually undermine inquiry. Our definitions can pluck knowledge prematurely off the vine, preventing it from ripening into wisdom. (p. 183, DTS)
The system that establishes 'levels' of time, space, and knowledge is itself a product of conventional understanding and cannot be considered absolute. . . . A hierarchical model risks the interpretation that Great Time, Space, and Knowledge are states to be arrived at, as one would arrive at the upper story of a house after climbing a set of stairs. (pp. 426-7, KTS)
The fullness of 'nothing at all' is the inseparability of Great Knowledge from Great Time and Great Space. Space allows the rhythms of Time to propagate, while Knowledge establishes the purpose or pattern. When one of these three is wholly unbound, even the distinctions of Time, Space, and Knowledge are absorbed in Being. (p. 492, KTS)
