Of course it's not one size fits all, but it can take TIME to find the size that fits your life...I've tried so many types of meditations and found one that fits me some yrs ago in the form of silent meditation group I was attending, we were even allowed to "lie down" to meditate, just don't fall asleep. So at home and my late age, I lie down and meditate silently....works great, and Wakes up my body and gives me a clearer mind....I don't deal with TBI but as I've said I believe it can help everyone......
