One-way and mutual aspects
Distinguish a single directional contact from two planets independently aspecting each other.
A full aspect is directional. Planet A can aspect Planet B without Planet B necessarily having a full aspect back to A.
A mutual aspect exists only when each planet, using its own aspect rules, reaches the other planet’s house/sign. The most obvious example is two planets opposite one another: each has the ordinary 7th-place aspect to the other.
Special aspects can produce one-way contacts. Jupiter may reach a planet by its 5th or 9th aspect while the receiving planet has no corresponding full aspect back.
Mutual aspect is one form of planetary relationship used later in the course’s sambandha and Raja-yoga audits. Record the geometry first so those later rule checks remain traceable.
Do not confuse mutual aspect with conjunction. Conjunction means same sign/house in this course; mutual aspect means separate positions with full aspect in both directions.
How to read it
- Check whether A aspects B.
- Independently check whether B aspects A.
- If both are true, mark mutual aspect.
- If only one is true, keep it one-way.
- Do not relabel the relationship as conjunction.
Key points
- Mutual aspect requires two independent true checks.
- Opposition commonly creates mutual 7th aspects.
- Special aspects can create one-way contacts.
Apply it to a chart
Mars in H1 and Saturn in H7: Mars aspects H7 by its 7th; Saturn aspects H1 by its 7th → mutual aspect.
Jupiter in H1 and Mars in H5: Jupiter aspects H5 by its 5th, but Mars does not fully aspect H1 → one-way in this profile.
Do not assume “A aspects B” means “A and B mutually aspect.” Check the reverse direction separately.
Apply this lesson to a chart
- Choose any two planets in D1.
- Check A→B and B→A separately.
- Classify the pair as no full aspect, one-way aspect or mutual aspect.
