Hi Ben. Thanks for your detailed response.
I've never done an extended retreat and doubt that the opportunity will present itself for years to come. But many years back i used to do about 2 hours of mindfulness exercises and meditation, every morning, as compared to only 20 minutes of meditation, daily, now, and mindfulness practiced irregularly.
During that time period (1987~93) i experienced a very deep sense of calm, relaxation and equanimity, with a definite reduction in anxiety and desires. Yesterday, listening to the Goldstein audio (linked) he described "body scan" exercises similar to what i had done for years, so today i've started to do them again.
At that time (87~93) i was not following the dharma, specifically. Peace and calm were my goals, so i'm interested in trying to get back to where "i wuz" and then continue forward, in the manner Buddha has shown and suggested.
Thus, these questions.
