Conjunction (Yuti)
Conjunction — yuti — is two or more planets sharing the same sign, sitting together and blending their natures into a single mixed influence
Conjunction — yuti — is two or more planets sharing the same sign, sitting together and blending their natures into a single mixed influence. Where an aspect is a glance across the chart, a conjunction is planets living in the same room: close, unavoidable, sharing everything. What the blend feels like depends on the company. Friendly planets in one sign reinforce each other and pull the same way; unfriendly ones jostle and pull apart, so the house they share carries a mixed, restless quality. A benefic can gentle a harsher neighbour, and a harsh planet can strain a gentle one — and the strongest planet, or the lord of the sign, usually sets the tone for the whole group. Closeness sharpens all of this: the nearer two planets sit by degree, the more completely they fuse, and a planet drawn too close to the Sun is swallowed by its glare (combustion). Numbers matter too — two planets make a blend, but several crowded into one sign pour a great deal of life into a single area of the chart, often a defining theme, powerful but hard to untangle. Read a conjunction, then, less as one planet plus another and more as a new compound with a character of its own.
The texts read conjunctions by their count and their company: Saravali and its kin enumerate every two-, three- and up-to-seven-planet yuti, and the fruit turns on the joined grahas' friendships and dignities — a Sun-and-Mercury union reads quite unlike a Saturn-and-Mars one. Benefic joined to benefic uplifts the bhava, malefic to malefic afflicts it, and mixed company gives a mixed result.

In a whole-sign rashi chart a conjunction is same-sign occupancy, and its quality is read from the joined grahas' natural and temporal relationships and their dignities. The engine grades closeness for combustion using the classical BPHS orbs (asta, engine 1.3.0) and resolves graha-yuddha — planetary war — between very closely joined planets (detected same-sign). Many named yogas are conjunctions by definition, from Budha-Aditya (Sun with Mercury) to the multi-planet Chandra and nabhasa combinations.
