The form is very strict, employing 108 basic movements and keeping the body upright from the neck to the hips, moving up and down using only the knees, and stretching to the rhythm of the music. A great deal of symbolism and importance is displayed in complex and beautifully executed finger and hand movements. Sometimes six-inch, especially designed, finger nails add to the effect and complement the splendour of the spectacularly ornate costumes. All of it combines to produce a hypnotic and memorable experience.
