Over on the Inglinga blog Wulf has posted two articles on the Helm of Awe and its connection to the Ario-Hindu Ashtanga Yantra symbol. Steed made an interesting comment regarding the English custom of placing a cartwheel on the side of the house for protection. In fact the Ario-Hindu's use a symbol called the Dharmachakra which is represented as an eight spoked wheel which symbolises the āryāṣṭāṅgamārga (Noble Eightfold Path -notice the root word Arya) - the symbol appearing as an eight spoked cartwheel.
The Sanskrit noun dharma comes from the root dhṛ, which means "to hold, maintain, keep" and takes a meaning of "what is established or firm" and hence "law". It is derived from the Vedic Sanskrit n-stem dharman- with the meaning "bearer, supporter" in the historical Vedic religion conceived of as an aspect of Ṛta. Rta is the root of Rite and Ritual via the word Rit. What is interesting is that this cognates with our own rune Rad (to rotate) which also gives the the words Road, which connects it to the Ashtanga Yantra.
