Dharma Wheel

The dharmachakra (also known as the wheel of dharma) is one of the eight auspicious symbols. It has represented the Buddhist dharma, Gautama Buddha's teaching and walking of the path to Nirvana, since the time of early Buddhism

The Buddha is said to have set the dhammacakka in motion when he delivered his first sermon. 

Buddhism adopted the wheel as the main symbol of the chakravartin "wheel-turner", the ideal king or "universal monarch", symbolising the ability to cut through all obstacles and illusions.

The Wheels most important symbolism, is that of Buddha's teachings.
