Om sai Ram Shivani,
Good to see that you could speak with your parents.You have taken the first step.
At least now your parents know what you want.What you need to do now is talk to them as often as you can.You know how you used to get adamant as a child when you wanted some thing.
So please talk to your parents again and again...showing them the reason for your decision.
The more you discuss this with your parents woudl actually show them the intensity of your liking / love for this person. Most of the parents want their children to be happy. explain them what if you get married to the guy of their choice and regret this for the entire life and not be happy.You have to make them realise that they are forcing their choice on you and not thinking of your happiness. ( You have to use all these arguements , and use them with conviction....and the more strong you are in showing them the reason...the better are the chances for their agreeing to your decision.Make them realise that the only purpose for them to provide you this education was to make you a confident woman, take your decisions independently and by forcing their choice on you...they are defeating the very purpose ) You have to think of 100 other arguments when you talk to them about it...and do your homework before you speak to them.
also, just be confident that you would get married to Sumit only.I am sure Baba is putting words into my mouth and he would make this happen for you.
Just wait and watch his Leela .
If you wish, you can call me at 98308-10004 and we can talk more about it.
Om sai sri sai jay jay sai.
