this is a very simple little meditation which is triggered by colours, just choose a colour and then picture something to meditate on - simple. Light a white candle and stare just below the flame picturing your image.
Red - power, love, sunsets, fire, roses, lips, strawberries, candle flame, cherries, dragon's breath etc etc
Orange - energy from above, oranges, tiger, bumble bee, goldfish etc
Yellow - bright minds, daffodils, banana, sun, sunflower, custard etc
Green - harmony, grass, leaves, emeralds, trees, jade etc
Blue - serenity, sky, ocean, butterfly etc
Indigo - rainbow etc
Violet - spirit, violets, pansies, etc
Be creative and enjoy.
