Birth Details: 3-Feb-1975, 21:55 Hours, Gidhaur, Bihar, India
In 2016 August, at the age of 42, the native lost his job. His role ceased to exist. Rahu had just started in Naisargik Dasa and Saturn the significator of the profession was at 8th from Rahu. Is this reasoning enough?
Also in sep 2021, native lost his father. Now assuming Rahu’s progression is 6 months per sign, in 2021 sep Rahu would be at 12th to its original position..namely in house #2. Rahu from here is at 1-8 position with 9th house..Could it be the reason for father’s death. This seems too simplistic. Could someone please explain this?

– Rahu dasha is showing sudden changes in routine and initiatives in life under transformative circumstances. (6L in 3H Sc).
