Get your mind right

From the Dhammapada:

"As irrigators lead water where they want, as archers make their arrows straight, as carpenters carve wood, the wise shape their minds."

The untrained mind causes all kinds of problems for us. It exhausts us by jumping around like a monkey and getting into all kinds of messes. How quickly it moves! Try to count the number of topics that the mind will touch in a single minute. Most people will give up on this exercise because it's almost impossible to keep up. This monkey mind can be trained. Meditation is recognised world wide as a method to shape the mind. If you have never meditated I'll give you a very simple, yet effective, technique to start with:
Sit upright in a comfortable position (don't worry with crossed legs, lotus position, etc.), close the eyes and begin to follow your breath. Use your imagination and see the breath moving into the body. Let the belly soften and extend with the inhale. Follow the exhale out of the body as the belly deflates. You can count the breaths if you like. The mind will wander off again but gently bring it back to watching the breath.
Yes, there are many more exotic techniques but a simple one is just as (or more) effective and can be done in almost any setting. Try this method for as long as you like and as many times as you like during the day. I'll suggest that you find a quiet place in the morning before you start the day. Initially it doesn't matter if you sit in a chair or on the floor. Over time your practice will take you where you need to be.
Don't wait any longer to try this. Begin right now, where you are and get your mind right.
