When love and hate collide

Since last evening my head is filled with thoughts. Questions which has no answers. In life i have learnt that having expectations is not worth a penny. When it doesn happen it hurts. Its not necessary that whatever you like with all your heart will happen. Generally what you least expect only happens. Ok i know i don make any sense here.Chuck it.
Ever heard of something like paying for all previous births' bad deeds. They say its KARMA. I find it quiet weird ok. I would've been a mean lady or bad man in my previous birth. But in this birth iam a sweet person (well everyone says so) then why should i pay now for wht i did in my last birth. Was telling my mom the other day that one must pay for what one does immediatly thats fair enough. She said its no more like that this is "Kalikalam" in which you pay the price immediatly. Thats better.
I knw 2 sisters who is in their 30s still unmarried . Now the reason why they didnt get married is because their ancestors have done something bad in their times for which their family is paying the price. How mean is that. But god is kind enough. All we have to do is do some prayashchit and the paap gets cleansed. So it means we are getting a chance to mend our past deeds and that of our ancestors. My parents go to temple everyday. I used to wonder why? i mean visitng god once in a while is fair enough why go daily. Infact i used to laugh it off saying that God will run away looking at you come daily and ask for something. But the fact is Faith in God is very important. He is the ultimate. My mom always says that if you truly need something pray with all your heart and god will definitely answer your prayers. Its a matter of time. It seems goddess parvathi did a lot of fasting,performed a lot of pooja inorder to marry lord Shiva. When goddess herself had to put maska to God then hum kis keth ke muli hai.
IF you are wondering what significance does my topic have with content,the answer is nothing. Its my favourite song by deff leppard.
