Achieving concentration is a kind of training process. You learn some things in life theoretically and some by doing them. Achieving concentration belongs more to the second kind.
When you sit to meditate, you quickly become aware of your endless mental activity, of your thoughts, emotions and physical sensation arising and passing spontaneously. Mostly you find yourself carried away by them, seemingly experiencing situations that have no real existence, such as what was, what will be, what should be and so on.
Sometimes this may constitute your entire meditation. It is anyway not under your control. However, at some point you may awaken from your dream to notice you have been thinking. At the same moment, you may notice a bird, a flower, your breath, things that are really there at the moment.
This is a moment of enlightenment, of awakeness. If you notice it, the quality of this moment is remembered slightly. Each time this coming back to reality occurs, it become slightly deeper, purer, more stable and more likely to occur again.
So to achieve deep concentration, access these moments as often as possible. It is important to remember there is nothing you can do to cause them to occur. But you may become ever more familiar with them over time.
This is meditative training.
Most people need a teacher to kick-start the process by pointing out reality until it becomes familiar. I recommend you to:
- Find yourself a teacher.
- Make yourself some quiet time every day, so that meditation is more likely to occur
- Spend time with like-minded friends who can support you on the way.
Enjoy the experience, whatever happens.
