Can I attain Vipassana without doing the body scan? I returned from Goenka's Vipassana retreat. The technique of being aware of sensations with equanimity was very helpful and led me into deeper states of meditation. 

But his technique includes scanning the body as you move deeper. What I found was if I am focused on sensations on my face then willfully changing the focus to shoulder disturbs meditation.

Also, I have to keep my mind active to control and move my focus with will, from say face to shoulder etc.

Else where as I read Ajahn Brahm, his whole technique comprise of 'letting-go' of 'doer' or 'will'. Main emphasis is about the attitude of not getting the 'doer' or 'craving' or 'will' involved. 

Further to the answers to my last question as I now understand we reach to Vipassana i.e. insight. So my question is can I skip the body scan part. Can I attain Vipassana and Jnana without involving the body scan. Just being aware of sensations on face bring a great deal of Samatha. Keep the doer, controlling mind aside.

I am sorry I am mixing Ajahn Brahm and Goenka. What is happening is I am finding it difficult to attain ggod meditative mind through AB's method of focusing on breath but I am doing good progress in sense of calming my mind and reducing the thoughts by Goenkas method to watch sensations through equanimity.

So my plan is attain Samatha through Goenka's method of watching sensations and then as I attain meditative mind with no thoughts switch to AB's method to attain Jnana. 

I checked other question-answers regarding body scan but they do not answer my question as their problem is not 'bringing in the doer' or 'will' their problems are different.

So my question is can I skip the body scan?
This is an old post, and I don’t even have an account here but I found this by googling to try to find out if there are other Vipassana centers or teachers practicing Vipassana the same way as the teacher in my town! (Jefferson City, MO, US, Vipassana Buddhist Church, Rev. Montee Dhammaruchi). I’ll talk about that a little and hopefully the info is helpful to someone!
It’s been years since I attended there, I traveled away for a long time and found other Buddhists doing different things in Portland Oregon. I practice shikantaza now, as a beginner, after finding that Dogen’s framework seems to click with my logic and also challenge me in a way that feels growthful.
But anyway, years ago, I practiced this form of Vipassana for about 3 years with Rev. Montee, and then continued in it independently until I switched to Zen. The instructions are to sit in a way that isn’t too straining. He encourages full lotus if possible, half lotus if you can’t do full, Burmese posture if you can’t do either. The point is ideally you are splitting your weight between two knees and your butt. Some people sat in chairs though, and he didn’t mind making those available. And then you try to isolate awareness in your breath, with all senses, focusing on your nostrils if possible. And then when sounds or sensations or thoughts happen, try not to be disturbed by them but be aware of their impermanence. That was basically my experience and understanding of it, and I haven’t learned or practiced any other form of Vipassana than what he instructed. Other Vipassana techniques sound pretty different when I read about them. The way Montee taught it, it never involved a body scan. Mindfulness of the whole body was encouraged but there wasn’t a systematic method like that. It may be that he was trying to streamline the essence of Vipassana. When I first began practicing Zazen I had a hard time differentiating between it and Montee’s Vipassana. I know that he had trained in Zen originally so maybe that’s why he taught this way.
