Rāja-yogaराजयोग(Raja Yoga)
Classical yoga-class produced by kendra-trikoṇa lord combinations; the foundational Rāja-yoga sovereignty register.
Rāja-yoga
Rāja-yoga (राजयोग, also written Raja Yoga) names the classical yoga-class produced by the combination of kendra-bhāva lords (1st, 4th, 7th, 10th) and trikoṇa-bhāva lords (1st, 5th, 9th) in relationships of conjunction, mutual aspect, or rāśi-exchange (parivartana). Classical tradition holds the kendra-trikoṇa lord combination to be the most auspicious configuration-class in the chart: the kendras carry the structural strength-register of the chart (action, home, relationship, career), the trikoṇas carry the merit-register (self, creativity and progeny, dharma), and their lords' active engagement with one another classically produces the sovereignty-register that gives the yoga its name.
Classical grounding
Brihat Parāśara Horā Śāstra treats Rāja-yoga across its yoga-phala chapters at length; Phaladeepikā chapter 6 consolidates the core rules; Saravali chapters 33–45 and Jātaka Pārijāta add extensive classical treatment. BPHS specifies that the combinations operate through functional benefic lords per the Lagna under consideration — the functional benefic status of a bhāva-lord depends on which bhāvas that graha simultaneously owns. The Lagna-lord carries particular classical weight because the 1st bhāva is counted both as kendra and as trikoṇa — Lagna-lord's own Rāja-yoga-forming placement is classically the strongest single-graha contribution.
Formation rules
Rāja-yoga arises through four classical mechanisms: (1) conjunction — a kendra-lord and a trikoṇa-lord placed together in any bhāva; (2) mutual aspect — the two lords aspecting each other (7th aspect by default; 4th, 8th for Mangala; 5th, 9th for Guru; 3rd, 10th for Śani); (3) rāśi-exchange (parivartana) — the two lords occupying each other's rāśis; (4) single-graha Rāja-yoga — a graha that owns both a kendra and a trikoṇa by virtue of rāśi-lordship (this occurs for specific Lagnas). Mesha-Lagna's Mangala is the classical example: lord of the 1st (kendra and trikoṇa) and of the 8th — here Mangala's 1st-lord function dominates.
Classical manifestation pattern
The classical Rāja-yoga register names authority, status, recognition, and prosperity in the domains signified by the participating lords. If the 9th-lord and 10th-lord form the yoga, the register classically inclines toward dharmic authority and career prominence; if the 5th-lord and 4th-lord combine, toward domestic well-being and educational distinction. The classical reading is registrational: Rāja-yoga does not guarantee political kingship but names the sovereignty-register that operates in the fields the participating lords govern.
Strength modulation
Classical rules for Rāja-yoga strength include: (1) the participating lords in own/exalted rāśi strengthen the yoga; (2) placement in a kendra or trikoṇa from Lagna further strengthens; (3) participation of dusthāna lords (6/8/12) weakens or corrupts the yoga — the mixture is classically named yoga-bhaṅga or Rāja-yoga with affliction depending on the severity; (4) aspect of malefics on the configuration modifies the reading; (5) combustion of a participating lord weakens the expression; (6) the Daśā-Antaradaśā of the participating lords is classically named as the period of yoga- activation — a Rāja-yoga formed at birth classically activates during the native's transit through the participating grahas' daśās.
