Namaskarams to you sir. I went through your Question answer section on Srardhhha KArmas

Namaskarams to you sir. I went through your Question answer section on Srardhhha KArmas and is indeed overwhelmed by your knowledge and authority. I would like to place a question before you about my proposed Rameswaram Trip. My elder brother passed away in 1991 and since he did not have any issues, another elder brother younger to him has been performing Hiranya Srardhham till date every year. The sastrigal informed that homam is not required and only hiranya srardham can be done. We are planning to be in Rameswaram to perform Thilahomam at the behest of my sister in law ( W/of the brother who passed away) in the last week of February. Kindly give me guidelines on the procedures to be followed while performing this Thila homam. My main questions to you are 1. Should it be performed by the person only if he is accompanied by his wife? or the male member can perform individually without the partner? 2. Is there any pre set procedure in our shastras for performing this thila homam as we are interested in performing it with complete Sraddhha to satisfy the departed soul 3. Is it performed only to a particular soul departed from us or it is performed in general for all those who left us? I would be much obliged if you can kindly answer the above sothat we can follow your advice and preform the rituals accordingly.
