Mutual reception
When Mars is in Cancer (Moon's domicile) and the Moon is in Aries (Mars's exaltation), the two planets are in mutual reception. Each has placed itself in the other's territory; the tradition treats this as a contract of guest and host. The pair acts in coordination, and either planet can lend its dignity to the other when interpretation calls for it.
What counts as reception
Reception by domicile is the strong form: each planet sits in a sign the other rules. Reception by exaltation is the second-strongest. Reception by triplicity, term, or face exists in Lilly but is weaker — usable as supporting evidence, not as a load-bearing claim by itself. Lilly's horary work weights mixed receptions (e.g., A in B's domicile while B is in A's exaltation) as still valid; the bond is established as long as each lands in some dignity of the other.
Why it matters
Reception softens hard aspects. A square between two planets in mutual reception is read as a tense but workable connection — there is a structural reason for them to cooperate, even when the geometry is difficult. It also rescues a debilitated planet: a peregrine Mars that receives the Moon, where the Moon receives Mars, draws on the Moon's footing.
Translation and collection
Two adjacent doctrines are translation and collection of light. Translation: a faster planet leaving aspect with one slower body and forming aspect with another conveys the influence between them. Collection: a third planet, slower than both, receiving aspects from two that do not aspect each other, gathers their threads. Reception strengthens both manoeuvres; without it, they read as weaker and more conditional.
How Netra uses it
The Receptions panel scans every pair of bodies for domicile and exaltation reception and reports the matches with the dignity each planet contributes. The Almuten and Aspects views surface receptions inline so a hard aspect with reception isn't treated identically to a hard aspect without it.
