While trying harder may help with many day-to-day tasks, with meditation trying harder makes the mind more tense, which defeats the very purpose of meditation. Once you cease making an effort, the mind will settle down naturally into a state of quiet.
The course takes you from basic practices of being present to some of the advanced techniques that Peter Russell has been teaching in recent years. They are simple to apply, but profoundly effective.
The Full Course is available on a "Pay What You Wish" basis.
