Meditation doesn't have to be complicated. In fact, it's often the simpler methods of meditating that are the most effective as you don't have to concentrate on what you're doing as much. Here are some simple meditation techniques that you can start straight away.
Breathing meditation
This is one of the simplest techniques but don't let that fool you. It's also one of the most effective techniques you can use to take yourself into a meditative state. You can start by simply noticing your breathing. Notice the air as it enters your nostrils and makes its way down your windpipe to your lungs. Is it warm or cool? Is there a "taste" to the air? How does its journey feel? Are you invigorated when you fill your lungs with air? There are more advanced breathing meditations available but this will definitely get you started.
Walking meditation
Another simple technique that is often overlooked for that very reason. Most people prefer to carry out their walking meditation in somewhere quiet such as a park or other green outdoor space but you can use somewhere busier if that's what you prefer or if that's the only thing available. Notice the feelings that go through your body as you walk: the ground below your feet, the air moving past you, the feel good factor that comes with any form of physical exercise. Then move on to noticing your surroundings. A lot of people find that by paying attention their experience is heightened and they notice things that would have escaped them or passed them by if they weren't actively concentrating on the experience. Almost as though they were taking part in a television show with the colors, brightness and sound all turned up fully.
