Another alternative is
walking meditation. It's my main form of "meditation" (mindfulness/awareness). I put in one hour daily, and then 20 full days each year during a couple of backpacking trips. If a person hasn't tried it, I can highly recommend it. Although I also think the "objectless, do-nothing" form of meditation is also a useful practice to turn off the mind and I try to incorporate that once in a while...
I think that in order to fully engage with the world (DO), one also has to "leave the world" periodically to "recharge the batteries" (DO NOTHING). I try to find the right balance between the two in my personal life.
Leucy, do you practice any form of meditation?
I don't think of that as meditation. You are actually stimulating your brain with activity, and just using that to try to stop thinking about your structured work for awhile. While you are not feeding yourself one thing to think about, you are feeding yourself another. In my time I have gone on hikes, both day and overnight, skiing, flying, travelling, etc... both solo and with someone. I find that it is more beneficial for myself and others to spend the time together. Either way there is a great deal of stimulation with the scenery and activity at hand. If I question whether you remember some of the things you've seen or done on your trips, I bet you have a memory of it.
In my past, I have meditated using bio-feedback, which is highly productive for clearing the mind and muscle tension, if that is what is desired. Any little thought can be measured and seen. Briefly for a time I enjoyed the ability to relax, and utilized it to destroy someone at a competitive game of racquetball. If focus is what you desire, and especially if you have attention deficit disorder, meditation is useful. People naturally learn to do it though, as they wish to. As I study, I look for a quiet place and prefer to not have the radio or TV running. When I am working I know that distractions like a phone call can be valuable, but my work is more focused without them. So then, recovery from a distraction is key.
Realize though, that a game of any sport, is highly reactive to a situation with an attempt to control something. Similarly, meditation is an attempt to control something. That is not necessarily a bad thing, but I don't wish to fully control my brain. In fact, I wish to interact with others through it.
A good mental exercise in my view is to be able to shelve thoughts for later. Either write them down or mentally go through the motion of putting it in a drawer so that you can return to it later. Then, when there is time, look at the drawers and choose what to contemplate. When the drawers are re-opened, some solutions and good ideas may have already been placed there. This technique also helps to recover from a distraction. You might have to immediately drop your train of thought, answer the phone and switch gears. When the phone is hung up, recovering the train of thought is quicker if you shelved it and picked back up where you left off.
In my view Lunitik loves an effect, and he has come to view that as ultimate, or as God. As you can see I have been challenging his notion from a number of angles. He similarly accuses me of doing the same, believing that I call my own sub-conscious... God. His form of meditation is purposely and intentionally solo. If a distraction pops up, in my view he is looking for ways to make the distraction go away. If the phone rings, ignore it, or answer it and say very little. Imagine having those two proverbial angels on your shoulders: one talking into your ear and telling you one thing. Another talking into your other ear and telling you something other. One goal of meditation can be to make them both shut up and go away. Ignore them. Don't talk to them and don't respond to them. If you argue with them, your mind will be filled with activity. If you ignore them, they will lose interest, go away, and you will have cleared your mind. Lunitik prefers to think that I have a sub-conscious on one shoulder, and an 'ego' on the other... both just physical manifestations of the human mind, and more to his point: calling 'God' something from it.
So then carry that into the real world. Can you go for a hike with someone else, who might say things that you do not expect, and for better or worse: distract you? And similarly, will you think of them, and say things to them that they did not expect, and similarly be a distraction for them? Would that be 'meditation' to you? Lunitik will go further to say that this exchange of information is damaging, and helping to prevent you from experiencing his form of the ultimate. At least at first, his form of meditation needs to be solo because it is purposely, in my view, a solo exercise.
