Chara kārakas, ārūḍha padas, rāśi dṛṣṭi and the sign-based daśās
Jaimini is not a supplement to Parāśarī technique but a parallel system with its own grammar. Where Parāśara assigns significators permanently — Guru always stands for children — Jaimini assigns them by degree, so they differ in every chart. Where Parāśara has grahas aspecting grahas, Jaimini has signs aspecting signs. Where Parāśara times by nakṣatra-based periods, Jaimini times by rāśi-based ones. And alongside the bhāvas it computes padas: the projected image of a house rather than the house itself.
The two systems are usually run together and cross-checked. They are not, however, interchangeable, and the commonest error is importing a Parāśarī assumption into a Jaimini calculation — reading graha aspects into a rāśi dṛṣṭi judgement, or treating the Ātmakāraka as though it were simply the Sun.
