I wrote about this 4 years back.
His birth details are not accurate. Even 2nd sept 1967 does not match to any event (but somehow PVR thinks it matches. I dont know how). Kalyan is fore sure a Leo Ascendant (Simha Lagna), who had a bad 20 years Sukra dasa during 1975/76-95/96. Generally Venus destroys education, attempts to have stable marriage, trials in glamour field for simha lagna born. But will give stardom and success in immediate Sun dasa (which happened during 1995/96-2001/02). He entered as hero and had his peak by summer of 2001 (Khushi).
Next is 10 years Moon dasa (2001/02 - 2011/12) which first brings gap in career and then a downfall from arrogant stage. After Khushi, PK thought he can direct a movie and took 2 years to make Johnny which flopped. Moon also gives unstable financial position, one stable relation (renu desai), break from previous relations (official 1st divorce in 2007-08), more downs and less ups in career (After 2001 and before 2012 only Jalsa was HIT). Even political attempts like CMPF, PRP failed.
Next is 7 years Mars dasa (2011/12-2018/19) which started with a big hit (Gabbar Singh) followed by next year one more hit (Attarintiki…). Mars also gives political/power connections. So he formed Jana Sena and did election campaign in 2014. His movie and political image remained intact till early 2018. He also had 3rd marriage during this period.
2018 started with BIG flop Agnatavasi (probably end of 7 yrs kuja dasa). Rahu dasa (18 years) definitely started in 2018-19 and no movies for 3 years (until vakeel saab in 2021), flopped 2019 elections. Now you can guess what will happen in future (next 15 years of Rahu)
