The previous night, though, I dreamed about interplanetary travel. I only have very vague memories about this (they were rather vague already upon awakening), and I don't recall, for example, the method of travel, except that it appeared to be more or less instantaneous. One interesting detail I remembered, though, was that our own sun (or solar system) was given the number 28 in some kind of galactic index system.
Given my interest in the occult, a number associated with such an important cosmic feature as the sun naturally caught my interest, and called for a little looking into. Does the number 28 have any special significance, particularly in relation to the sun? (The importance of the sun itself, of course, both occult and otherwise, is obvious.)
One of the first things I noted was that 28 is a 'perfect number' (i.e. 'a positive integer that is the sum of its proper positive divisors'). It is only the second perfect number in order, the first being 6. And 6 of course has a connection with the sun, as the Sephirah associated with the sun is Tipharet, the sixth Sephirah.
In numerology, the digits of a number are commonly summed up to get a single digit number. Summing up the digits of 28 we get 10, which in turn leads to 1. Considering the Sephiroth, these are of course interesting numbers, the first Sephirah, Kether, being the source of existence, the pure light that illuminates the sun (which in turn illuminates the moon, thus forming the middle pillar of the Tree of Life.)
Still keeping with the Sethiroth, 28 is the mystic number of Netzach, the seventh Sephirah, which is associated with the planet Venus, and thus with nature, love, creativity etc. The connection to the sun isn't the most obvious, perhaps, but the sun is, of course, our source of energy, the prerequisite for life on planet Earth. The dream did of course occur close to May Day/Beltane, a celebration of the coming summer. (Interestingly, looking at my astrological charts, transiting Venus is also currently in conjunction with my natal Sun.)
Also, on the Tree of Life the 28th path is associated with Aquarius. Which of course raises the question of the so-called Age of Aquarius. This isn't a concept I've ever really spent much time exploring. It is obvious, of course, that a great change in society has occurred over the last century or so, and symbolic concepts like this (or Crowley's new Aeon of Horus, another name for a similar concept) are of course interesting. (The sun, of course, has already passed through Aquarius some time ago, even in sidereal charts, so there is no obvious current astrological symbolism here.)
Lastly, consulting Crowley et al.'s Sepher Sephiroth, we learn 28 is the gematric (qabalistic numerology) value of Hebrew words for 'clay', 'unity' and 'power'. The latter two, at least, seem to fit well with the sun.
Now, whether any of this actually means anything significant at all is a good question, of course. But thought exercises like these are always interesting.
