Ketu the major karaka for Jyotisa

"Palasha Puspa Sangasham Tarakagraha Mastakam
Rowdram Rowdratmakam Ghoram Tam Ketum Pranamamyaham"
Meaning
I offer my obeisance to the violent and fearsome Ketu who is endowed with the potency of Lord Shiva and having a complexion resembling the flower of a palasa plant, he serves as the head of the stars and planets.

-------------------------

'Ketu' is said to be the causative planet for intuition. Basically Ketu makes person more introvert and seeks answer from inner conscious rather than like of rahu from outer world. Hence this planet has said to be one of the major significator for Jyotisa.

Hence Ketu if placed in trine (1,5,9), 12th , 2nd to Lagna, Moon or Sun is helpful for those who are doing Jyotisa. Even if Lagna, lagnesh, Moon or Sun is in Nakshatra of Ketu; promotes Jyotisa.

For Mesha, Meena, and Simha Lagna ; Ketu in 5H is best for Jyotisa.

Ketu trines to Saturn or Jupiter in Artha Trikone (2,6,10) also promotes career in Jyotisa, Karm Kand, religious sector.

Any association with enemy planet with Ketu with cause hindrance to said factors.

------
All planets play some or other role for Jyotisa. so chart as a whole should be consider for final delineation.
