A deeper study of the sun suggests the four directions of lines that are formed around it. It is this sign that is the origin of the symbol of the cross. The ancient traditions prove that the idea of the cross existed in the East long before the coming of Christ, especially among the Brahmans. It is from this sign that the two sacred arms were made, Chakra and Trissoun. Islam, the religion which allows no symbolism, has in the building of the mosques the same symbolism of the sun. Whether the name of the sun be written in Persian or in Arabic, it makes the form of the mosque.
