There are many ways to meditate. I will show you one way I use to do it when I was struggling.
Find yourself somewhere to relax. Once you are nice and relaxed you will need to light the candle. The candle can be any colour you want it to be, doesn't really matter when you are using this exercise.
So, once you have lit the candle. All I want you to do is to just focus on the candle flame for five minutes straight.
Once the five minutes have came up. I want you to close your eyes and see the candle flame in your minds eye. Focus on the candle flame. Stay focused for as long as possible. You might realise that your thoughts are beginning to vanish. If you don't do it the first time keep on practicing.
What do you benefit from this exercise?
* you will start to build your focus up.
* better visualiseation.
Keep on practicing.
