Is it OK for children to do meditation? And have you got any suggestions of books where we can find meditations for children
Yes, it's fine for children to meditate. Remember that the number of minutes that they can hold their focus is two, plus their age. So for very young children, it would be quite a challenge to meditate for longer than five to ten minutes. However, someone who is 13 years old could be able to meditate for twenty minutes. Many of my meditation tapes and CDs have been used successfully for 13 year olds. However, if a parent wants to teach the techniques to their 7 or 8 year old, then I suggest they modify and shorten the meditation.
As to suggested books, the words to meditations are printed in each one of my books. I have found useful the following books by Maureen Garth, published by Collins Dove-Victoria
4. The Inner Garden (Meditations For Life From 9-90).
How long and how often should I do the meditations from the CHI book
Basically, the answer is that it is an individual choice. For some people doing each meditation just the once is sufficient. For others they feel they may like to do it a 2nd, 3rd (or more) time - especially in the area of forgiveness. It's a good idea to do any meditation at any time that you feel the need, and to make it part of your life.
How do you know when you are in the meditation state
The most common method is by not being able to feel your body. Your mind is extremely aware and you're in total focus - you just lose the awareness of your body. Another way that some people can tell is by their arms feeling either extremely heavy, or light - likewise their legs. Another way that some people can tell is that they can actually feel their REM (Rapid Eye Movement).
What relevance are the colours during meditation
Colours vibrate - red, being the outside of the rainbow, vibrates with a much greater wavelength than orange and then orange is greater than yellow, and so on. So when you go through the colours of the rainbow, starting from red and finishing with violet, then this is used as an induction process to take you from the Alpha brainwave state to the Theta state. The Theta state is the meditation state. As we go through the colours the vibration is getting finer and finer - this is what takes us deeper.
