Shashtiamsa

[3] Venkatesa in his Sarvartha Chintamani (Slokas I.29 & 112) explains that planets occupying cruel Shashtiamsas (1/60th division of a sign) produce evil results, planets in good Shashtiamsas, and which planets are also occupying good vargas or divisions become powerful to confer good results and that planets in exaltation, in friendly signs, own navamsas , own rasis, drekkenas, shodasmsas and trimsamsas possess Sthanabala and exercise the most favourable influence.

The same text also states that those planets that are exalted or occupy their moolatrikonas vested with full strength destroy all their good effects in case they happen to occupy cruel shashtiamsas.

Benefic planets occupying cruel shashtiamsas do not confer good results during the course of their respective dashas or antra-dashas.

If at the time birth Saturn is in its sign of debilitation or in inimical sign or is eclipsed by the Sun and is associated with and aspected by planets and situated in a malefic shashtiamsa one meets a miserable death.

[5] Saturn occupying its own sign or exaltation sign does not generally afflict the natural benefics or their yoga-formations, and if not occupying its neecha navamsa (Aries navamsa) or a cruel shashtiamsa confers good results.
