A lot of girls love stuff that is kind of “new agey” and mystical. Of course, this won’t work on every woman, which is why you’ll need to ease yourself into the gambit.
The first thing you’ll need to do is learn a bit about palm reading lines meaning. Just study the basics, and what the various lines mean. Google is your friend.
Next, you’ll need to get from where she is, to you holding her hand and telling her future. This is no mean feat. You can’t just walk up and say, “Hi, I’m Bob! Give me your hand and I’ll tell you your future!”
While it might work, you’ll need to ease yourself into it. This works best when she’s with a group of friends. Once you get plenty of success with this in groups, you can start using it on individual girls.
The best approach is to break her state, preframe your introduction, and then ask her permission. Now, asking for permission isn’t going to put you in the “beta” frame unless you are overly solicitous. Just make sure you phrase it as a “softener.”
Say something like this, “Excuse me, I couldn’t help noticing you. I know this is going to sound incredible strange, but… you seem to have a certain energy about you. In fact, you remind me of this girl that had an incredible future. In fact, I read her palm, and many of the those things came true.”
Notice a couple of things. First is that there’s a pause in there. This will create curiosity. Next is that you’re already saying this is strange, so if she thinks you’re strange, you will have already said it, so it will sound normal. Next is you’ve mentioned that you’ve done this with a previous girl. This will take away any idea that it’s some kind of pick up line.
Next, when you describe the previous girl, you’re being incredibly vague. She’ll almost certainly be incredibly curious. Then if you ask her if she’d like her palm read, she’ll almost certainly say yes.
Of course, then it’s up to you. Mention a couple of obvious things, and then ask her for some feedback, which she’ll happily give. Make sure to keep it vague. Compliment her on her “energy,” and tell her she’s got a bright future.
How do you close her? Say something like this:
“Look, I don’t know if you believe in destiny or anything, but I had a really good time talking to you. I think you’re a really interesting person. I’d like to get together with you later for a cup of coffee or something. Give me your phone number so we can get together.”
