hi Sai Follower, from this forum i found that writing "OM SIDDHA SANKALPAYA NAMAH" 108 times every day for 41 days will help you get the grace of Lord Sai in getting married with ur loved one. Also, do satcharita parayana in 7 days i.e, saptah and if you have time, repeat the saptahs (start on a Thursday and finish by wednesday).
I did many of these but invain ..he got married to someone else. But i sincerely wish and pray that all your prayers will bring you the reward u r expecting. All the very best.
