Kaal Sarp, Mahamrityunjay and Graha Shanti at Ujjain
Ujjain is a jyotirlinga kshetra, and what is asked for here are the anushthans the tradition ties to Mahakaleshwar — Kaal Sarp Dosh nivaran, Mahamrityunjay jaap, and the graha shanti done at the kshetra rather than at home.
At a kshetra the tithi does more of the deciding than the calendar does. Nag Panchami and the Shravan somvars bring crowds that make a quiet anushthan difficult, and a Kaal Sarp nivaran is in any case placed on a tithi read from the chart rather than on whichever day the family is free. That is why the Kundli comes before the travel booking here, not after — the opposite of how the journey is usually planned.
Send the birth details first. The tithi is read from them and the travel is arranged around whatever comes out — booking the journey first is how families end up waiting in Ujjain for the right day.
