Ever since Leo did his "Do Nothing" and "Strong Determination Sitting" videos I practiced these techniques very rigorously and I attribute fast spiritual gains especially to strong determination sittings. In the beginning I was kind of shocked of how direct this method is in releasing illusion. I just recently found an great analogy that explains especially why such a technique can bring you so much clarity so fast. In an Alan Watts Lecture he mentioned that he has looked into the "act of torture" and makes the point that the worst part of torture is the beginning. Because in the beginning the victim is full of all his illusions and dramas. As the torture proceeds the victim over time seems to get in this drunken masochistic state in which he actually starts to get pleasure out of the pain. I find this analogy kind of useful to explain what happens in strong determination sittings. You start off basically with all of your beliefs and are just taken through the rudest kinds of pains 'till there is nothing left then plain it. I personally found that there is a state in these sittings in which you completely surrender to the pain, you just give up and take it all in. You completely accept that you don't know when it'll stop, you accept the roughness of the sensation of pain and see it just as it is. After doing this dozens of times your view on pain seems to dramatically shift. You have seen through a lot of pure illusion by just surrendering and bringing yourself to the end and what it will leave you with is this great sense of groundedness. I attribute most of my gains that I have made so far in very long and very intense strong determination sittings. I hope i could inspire you guys, let me know what you think of it? Something to try, or maybe a little to harsh for you? A little to direct? For me personally I found a lot of beauty in this very simple task. I found the Alan Watts analogy in this video. Highly inspirational for me.
