HI madam,

You can plan to perform the rahu kethu pooja on sunday during rahu kalam to get the good results

Thanks

HI sir,

Please perform the pooja with the proper guidance sir then you will get the good results, please find the proper procedure below:

Procedure to be followed for Rahu Ketu Pooja

1) A day before pooja, one should sleep on floor
2) Next day morning after taking bath, reach Temple and do Abhishekam with Milk to the Idols at Rudra Padam ( which is 100 ft from Pathala Ganapathi Temple) and do 3 Pradakshinam to the Idols.
3) After Abhishekam, please perform Rahu Ketu Kala Sarpa Dosha Pooja
4) After pooja, please donate 2 -3 meal packets to the poor.
5) Now you are good to leave home.

No need to change clothes. Not required to sleep on floor. You can do one thing, after arriving at Kalahathi, try to perfrom abhishekam to the Idol at Rudra padam with 1-2 liters of milk. Just sprinkle milk on the idols which is not reachable to you.

Why I’m suggesting Rudra Padam is , right from the beginning of this temple , Rahu Ketu pooja to be conducted here so these idols holds actual power.
As crowd is increasing so they moved Rahu Ketu pooja process inside Halls. So it is advisable to perform abhishekam and do 3 pradakshinam.

After this you are can purchase ticket from the counter and perform pooja. After pooja, try to donate 2 -3 meal packets to the poor. With this you will get complete benefit from the pooja.

Thanks
