யோகக் காரகர்கள் - பிருஹத் பராசர ஹோர சாஸ்திரம்

8-10. Natural Benefics and Malefics. Guru and Sukr are benefics, while Candr is mediocre in benefice and Budh is neutral (a benefic, when associated with a benefic and a malefic, when related to a malefic). Malefics are Surya, Sani and Mangal. Full Candr, Budh, Guru and Sukr are stronger in the ascending order. Weak Candr, Surya, Sani and Mangal are stronger (in malefic disposition) in the ascending order. In revealing maleficence, due to rulership of Kendras, Candr, Budh, Guru and Sukr are significant in the ascending order.

11-12. Lordships of Kendras and Konas. If there be an exchange between a Lord of a Kendr and a Lord of a Kon, or, if a Lord of a Kendr is yuti with a Lord of a Kon in a Kendr, or in a Kon, or, if a Lord of a Kon is in a Kendr, or vice versa, or, if there happens to be a full Drishti between a Lord of a Kendr and a Lord of a Kon, they cause a Yog. One born in such a Yog will become a king and be famous.

13. If one and the same Grah gets the lordships of a Kon, as well as a Kendr, or, if a Grah is in a Kendr, or in a Kon, it will prove specially a Yog Karak.
