in which term sade sati is a gain period

thank you for your query…Sade sati is a transit of saturn unlike a dasha…but if we want to calc the results there is an old system mentioned in Shani chalisa.but it is a classic and best way to analyse..Charan and waahan of Shani and dasha and transit all results are coded in it…stating “wahan Prabhu ke saat sujana jag digajj gartab mrug swana” example is gaj waahan Laxmi gruh aawe hai te sukh sampatti upjaave” when Shani comes riding an elephant it brings along Laxmi sukh and sampatti Prosperity…for Charan it states…”taise chaari Charan yah naamaa swarna loha chandi aru tamba” meaning when Shani comes on gold or silver or iron or copper steps…and results are mentioned…Shani chalisa also talks about how he behaves in its dasha as well along with Sade sati…further from karma perspective whether the manifestation or execution will be krur or subtle will depend on natal chart placements and actual intentions of the native…its mostly said that in the last dhaiya or last stage of Sade saati shani becomes little easy on native if native learns it’s life lessons and takes honest efforts and still remains ethical throughout the Sade saati timeline…also in Aquarius or Capricorn signs …Shani gets more of go getter and active in his task master side…but with Aquarius check rahu placement bcoz rahu n ketu are shanis puppets so they will play along in Aquarius…hope I answered well…if you want me to share the complete meaning of Shani chalisa then let me know…Shani is my fav and atmakaraka also…i respect Shani a lot.and it makes me happy to share more on shani…god bless…jai mahadev maa gauri
