The ROOTS of the category of Thunder in the universal IC are in a generic sense of expansive
binding, to share time with another/others but moving outwards. The overall
focus is on use of a sense of the new, sudden, the moment of 'enlightenment' etc - and so a focus on time with
others (and that focus on sharing ideas etc). Emotionally there is a link to surprise.
24 - returning, the new (unconditional)
27 - hungering (conditional returning etc
- QA control on skeletal forms)
03 - sprouting (unconditional)
42 - augmenting (conditional sprouting, the
act of changing levels etc)
51 - enlightening, surprising, shock (unconditional)
21 - problem solving (conditional enlightenment
etc)
17 - believing, following (unconditional)
25 - dis-entangling (conditional believing,
following one's own path without fear and/or consideration of consequences)
ALL of these can be interpreted negatively or positively. In the above pairs of the thunder octet, the first hexagram
is
unconditional in its manner, the second is conditional. Thus, since this octet reflects in a microcosm the macrocosm
so the 'opposites' dynamics of the macro apply. Thus we have pairs of hexagrams reflecting the unconditional/conditional
expressions of the five lines each hexagram shares with the other:
24, 27
03, 42
51, 21
17, 25
As well as the mapping of POTENTIALS/ACTUALS, or more so the seeming 'balanced' as compared to their exaggerated
format:
24 - 25 ('return' to the faith vs exaggerated form - stand up and publically assert)
27 - 17 (basic finding of skeleton of 'faith' vs exaggerated form, seeking out and commit)
03 - 21 (generic issues in beginnings vs more exaggerated forms of 'problems solving')
42 - 51 (basic augmentation of level change vs strong 'enlightening' experence)
All have a sense of dealing with issues of the new, the enlightening, shocking etc as a 'fundamental' element.
The skeletal forms (27-ness) of all of these hexagrams are found in the octet
of earth.
The PAIRS themselves form into quartets of meaning ((24,27),(03,42) Vs (51,21),(17,25)) and so on. (e.g. more pairs
such as 51,21 vs 17,25 - meaning in meaning in meaning - all due to the method of derivation)
