Energy Centers on the Tree of Life.

[Plenum]

Ra: I am Ra. This is basically incorrect although you are upon the correct track of thinking. Each of these stations has a complex number and shading of energy centers as well as some part in various balances; the lower, the middle, the high, and the total balance. Thus there are complex colors or rays and complex charges, if you will, in each station.

one of the reasons why I think this is the case is that let's take a look a look at one of the stations - Chochmah.

here's one definition.

"Chochmah is the second Sephiroth. Chochmah means 'wisdom'. It is the Word, the Logos. It is the Son in relation to Kether as its Father. Remember Chochmah is on top of the right, positive, male pillar, and thus Chochmah is considered to embody the primal male energies. It is the active, male principle, the vital, energizing element of existence. In Chochmah is the will to create."

Wisdom could be seen to be identified with blue ray, but as a generalised concept, wisdom can also be seen through the lens of red ray (survival), or personal sovereignty (orange ray), etc etc.  

Actually, looking more closely at the definition above, Chochmah would probably better be approximated with "Co-Creator', which is still a blue-ray quality.  But the same creative, flourishing instinct can be seen through the lens of different rays.

Hence the one station (and working with it in different contexts) could help balance various issues in different energy centres.
