A lesser triangle behind series G
See series G triangles:
The hint is that this triangle—via the precessional transfer to Aquarius—represents the grounding of Aquarian age ideals through the rulership of Venus’ in the last decanate, which is first on the reversed wheel. Just as Venus was:
responsible for the appearance of… individualised consciousness… Venus will again have an analogous influence [except that] the emergence into manifestation [via the 7th ray of Uranus] of an increased individualism and self-conscious realisation will be subordinate to the appearance of the first stages of an expanded consciousness throughout all mankind—the consciousness of group responsibility… perhaps better expressed as a form of group individualism.
Therefore: behind all these events, the dim outline of a lesser triangle… can be seen… a blend of the energy of three planets [producing] a combination of the energies of rays 3, 5 and 7 (active intelligence, ceremonial order or magic, and concrete mind).
