If we depict yoga in the form of many-spoked wheel (Fig. 1-23), then the spokes. Represent the different schools and movements of yoga, the rim symbolizes the moral requirements shared by all types of yoga, while the hub stands for the ecstatic experience by virtue of which the yoga practitioner transcends not only him or her own limited consciousness but cosmic existence itself (Fourteen, 2002).
