I started with it a few months ago and it has been a journey
At the beginning I went to our Buddhist Center in Town and also started it at home in the morning. And well, I have to say one can do several small meditations throughout the day.
I believe if one has time to do it 4 hours a day, faster progress is most likely and a great example of will power!
I am far away from that still! Yet, I have a sincere question as I am still a beginner in all of it. After a few months meditation I noticed a few changes which kind of came by themselves, examples : I needed less sleep, ate more fresh veggie/fruit, was generally more relaxed and not affected by stress around me, thoughts come a bit clearer to me then before and i think of things in different ways.... I stopped doing the meditation in the Buddhist center because I started sailing
I then noticed that things went back to before.....
So what I do now, is having a few mini-meditations while I walk to work, or when I wait for the bus or when ride the train, and 1-2 week I meditat e in the park.....the effect is the same again
Now, is it necessary to follow certain rules or orders or is it enough to just aim for calming the mind?
