I do believe in love. In its existence!
I believe in love the same way I believe in jinns and bhoot.They too, exist even though I havent come across them in my 23 years of breathing on this Planet. Both these things are co-related to faith.
Experiencing them, however, is a totally separate issue and I wouldnt be able to comment on it because I havent been (un)fortunate enough to go through it yet! Awaiting the experience, oh yes, I definately am!
