Similar to a few of the above answers, I try to maintain a calm and unmoved meditative state of mind throughout my entire day. Nowadays I don't have as much time when I'm home alone for the entire day, but when I do have a chance to perform more focused meditation, the low end is 30-60 minutes, high end 2 or so hours for unaltered meditation. During my entheogenic/psychedelic experiences I prefer to spend such states in deep meditation and as such, have gone on for as long as 6-8 hours.
