You'll get the most advanced, state of the art chi technology when you register for a summer retreat at Big Indian. And you'll get it for a full 5 nights, six days. Most people need a week to really build up to a breakthrough in their chi training. Weekend seminars just aren't as powerful. Books and videos are a fine introduction, but they can't answer your personal questions.
Most people learn quicker and better with a live teacher.
Because thre is a live transmission of chi from a teacher to student.
