Triangular gazing is a particular form of eye contact that the PU community has always been drawn to, however I haven't seen it mentioned on here for a while. Since game is always evolving, especially on seddit, I'd hate for what I consider to be a useful tool to fall by the wayside.

Rather than explain it myself, I'll leave it to the (Westsidetoast)masters: http://westsidetoastmasters.com/resources/book_of_body_language/chap8.html

The information regarding triangle-gazing is about two thirds of the way down the page (why I didn't want to just post the link), however I think the whole e-book should be essential reading, there's so much of value.

It is a field-tested technique, just search Triangle Gazing and you'll find it on forum after forum. My personal experience with it has been good, it's a good way of leading because girls often mirror it, also if she's triangle gazing the shit out of you while you're in each other's personal space it's a solid indicator she wants to kiss.

As for the power gazing, I've used it on three AMOGs in the past, one was completely unfazed, one literally started sweating profusely and the third got somewhat confrontational. So I would neither recommend or discourage using this.
