Why, in a set of documents concerning Esoteric Wisdom...
...is there a section regarding these dimensions and this kind of study?
Because Kendo Nagasaki asserts that these hard, intellectual pursuits can yield a great deal of understanding about the nature of the physical world in which we live, yet they rely to a surprisingly large degree upon insight, intuition, and inspiration – properties and qualities which cannot be encapsulated by the “hard” sciences, but which can be bridged by the Kendo Nagasaki Spiritual Wisdom.
Mathematics can prove many things, but it relies upon imagination to give rise to the concept which mathematicians seek to establish; without an inspired, intuitive insight into metaphysical states, mathematicians could not plan how to prove them.
Even cutting-edge metaphysics begins as a philosophy – and it remains a philosophy until mathematics can avoid tripping over itself as it attempts to “prove” the theory. This is the problem that was found to occur with string theory – all the mathematics and the models of how things could work looked very promising, but the final mathematical proof could not be nailed down, so string theory remained a philosophy.
A popular question which arises among thinkers is to ask, “Is time linear?” To pursue the scientific approach, one would first have to define time – is it the investigator’s personal experience of time? And, will it be assumed that all time has the same properties as that time? And more – how closely does the investigator’s perception of the sequential nature of events approximate to any useful definition of time?
The foregoing paragraph illustrates how deeply one must think about scientifically investigating anything, and it can become enjoyably engrossing. There can be a temptation, however, to rationalise everything in this reductionistic way, and forget that a scientific description of a subjective state does not equal the experience of the subjective state (see Mind, Body, Soul, Spirit). As long as this is remembered, the intellect can usefully probe the fabric of reality – and should attempt to do so; because you have the ability to imagine yourself inside a black hole, you should do it, and see where it takes you! Philosophical "thought experiments" provide excellent exercise for the mind, and are able to quickly reveal some of the limitations of an intellectual framework of reality.
Perhaps the most enlightening perspectives on metaphysics occur when it no longer applies - when deep in meditation and the structured world fades completely away, when experiencing the so-called "slip-second" on the cusp of timeless nirvana, and, indeed, in an out of body or near-death experience, when all is known to be connected regardless of time and space.
The foregoing does not detract from the value of time, space, and metaphysics as mental tools, but instead reinforces the flexibility that is required when exploring the conceptual nature of existence - and thus, the metaphysical nature of existence is revealed.
Thanks to his deep appreciation of the concepts underpinning how existence is rationalised, Kendo Nagasaki understands that they are often unwieldy and clunky tools, limited in scope for feeling one's way through life's subtleties, and consequently he has a meditative approach to going beyond them and into the more fluid and intuitive appreciations of existence, some of which is explained on his Mind, Body, Soul, Spirit pages. In this, as in so many ways, Kendo has the answers!
