Mastery    Compare

I'm doing it just now and it is great.

But on disc 4 of the Approaching women in bars and clubs there is a Tyler section on social construct that blew my mind So I'd also look that up.

I bought David D's mastery series as well - and I think it's an excellent tool for your inner game. It's definitely not for newb's who are just getting to the rAFC status - stick with David D's "Double Your Dating" book first.
I love his thoughts on centering yourself and becoming a more powerful individual. I love his thoughts on "Status" as well, and how Rick H. complimented that with "If you're not qualifying her, she's qualifying you" - it's an absolute fundamental aspect of inner game during the approach.
I think the most powerful guest speakers on that were definitely Mystery, David X, and Rick H. I love the playful but confident "I-don't-give-a-****-what-you-think" attitude of David X. Rick H's stuff is a little more advance (esp the threesome stuff), but it's great to look at his carefree attitude.
It's expensive, but if you can get a good deal for it on ebay, its a HUGE piece of the puzzle. Covers alot of inner game stuff that the MM might not address.

I listened to the Mastery series and I found it to be an increadible resource. There are many guest speakers the ones that I liked the most were Mystery, TD(social proof and conversational threads), 26(funny as hell - cell phones, fun games and not just slapp hands or thumb war), Marie(womens prospective), Amber(heart connection - amazing), Rick H(talks about bisexual women and your reality), Tari(identity and mindsets) and David X. There were many others but cant remember their names. Mystery talks for about an hour about his M3 model and then does a quick Q and A. But he is better on David D's Body Language DVDs. TD has lot of the RSD guys come up and talk for about 5 to 10 min each and TD talks for about half hour or longer maybe. One thing a really like about the mastery is that it covers so much. There is about 20 hours of matierial. Most of the series is about inner game, the wussie, identity (great), reframing, instant gratification (talking about doing things now that will make you better 5 years from now instead of focusing on the short term. very interesting), status (this explained alot about people, AMOGs and community after seeing this you see social interactions totally differently), personality types, repport, and your purpose. This was better than the advanced series. But kind of expensive. If have the money or you are just starting out in the PUA community get it. If you are already running solid game and you can use MM effectively i woudn't get this product. Instead I would get some of the interview series.

I have some of interview series and I especally like TD, Craig, and 26. Hope this has been helpful.

Personally, Cocky and Funny and the mastery series program area very good for beginners. Thats actually gotten me into this seduction community yup. But is also for me the time to leave the community.
