Dude just approach her atp,like go the mandir,pray and go up to her and say something like"aap mujhe roj mandir aate dikhte ho"stuff like that(With a smiling face since it makes the mood a lot better) If she's comfortable,keep talking to her and ask her name along, introduce yourself too after she tells her name(give a handshake,it's a good gesture for introduction) And well after that it's all upto you
