The Collective circuit group

The Collective group consists of two large circuits — Understanding (Logic) and Sensing (Abstract). Its key theme is sharing: the need to express what people think, what they have lived through, what deserves attention and what doesn't. The Collective is quick to share thoughts, decisions, criticism and discoveries — but not personally: it is transpersonal and doesn't wait for feedback. That is why collective sharing is best not taken personally, even when it feels that way.

The Collective establishes what is best for the majority, even if it isn't best for a particular person: “What is good for all is good for each.” It is what made large societies with shared laws and customs possible.

Logic — a view toward the future

The logical circuit looks ahead: it wants to understand how everything will work going forward. It sees patterns, doubts, tests and refines: “I understand. I have the facts. This is how it works.” Logic is an experiment: it shows how things should work and demands that a pattern hold up to the test of repetition.

Channels

Logic (63–4), Acceptance (17–62), Judgment (18–58), The Wavelength (16–48), Concentration (9–52), Rhythm (5–15) and The Alpha (7–31). Together they form a path from doubt and formulation to mastery, correction and leadership for the common good.

Pitfalls

Sharing without an invitation, criticizing at the wrong time, pushing with facts. Sharing should bring satisfaction, efficiency and change — and it works better when you have been asked to speak.

Your understanding is valuable when it is asked for and when it serves everyone.
