When a slower planet receives aspects from two faster planets, which are not themselves in aspect. In Horary astrology the slow planet collects light from the faster planets and implies the matter can be perfected through a third person or intermediary. Traditionally, the fast planets must 'receive' the slow planet in their Ptolemaic dignities. i.e. the slow planet must be in an area of the zodiac where the fast planets have dignity. Used today in horary astrology, and as with translation, when two ruling planets in the horary chart are of no use in answering the question. Collection establishes a relationship between the planets and gives an answer to the question. Example: Venus at 18?° Leo, Mars at 15?° Leo, and Jupiter at 23?° Scorpio. Venus separates from a conjunction with Mars but both planets successively square Jupiter, which collects their lights.
