One of the prettiest features about Sikkim is the presence of colour in the state. Every street and road is filled with prayer flags of different colours. The Buddhist for centuries has planted these flags outside their homes as well as along the path that they travel for the wind to spread the positive vibrations of the flag across the countryside. The flags are said to bring happiness and prosperity. The 5 colours of prayer flags represent the 5 basic elements: yellow-earth, green-water, red-fire, white-air and blue-space. Balancing these elements externally brings harmony to the environment and balancing them internally brings health to the body and the mind. The various coloured flags are said to purify the human soul.
