Dharma Wheel (dharmacharka).

The wheel symbolise the Wheel of Buddhist Law, the endless cycle of birth and rebirth. The early Dharma Wheels followed the India tradition having many spokes as shown by this Dvaravati style from the 7th - 9th century.

Modern versions of Dharma Wheels often have four spokes, symbolizing the Four Jinas or the four ‘moments’ in the life of the Buddha; or with eight spokes, or octagonal, symbolizing the Noble Eightfold Path:

1. Right View

2. Right Intention

3. Right Speech

4. Right Action

5. Right Livelihood

6. Right Effort

7. Right Mindfulness

8. Right Concentration
