"Out of the 8 petals (limbs) of yoga, the only petal that is exhibitive is the yoga asanas whereas the other petals are very individual and personal. As such there is nothing wrong in holding a competition on the qualitative presentation of the yoga asanas. The presentation must be very natural with innocent and humility rather than pride and arrogance. Then I consider such competitions as healthy. It should be competition on the artistic level and not on egotistic body cult." 
-B.K.S Iyengar
