Contemporary Zoroastrian Scholar's Approach to Towhid

The contemporary Zoroastrian scientists consider Towhid as the most important principle tenets. They believe that Ahura Mazda is the only creator of the world. They say Ahura Mazda has all attributes of perfection. Also they sometimes refer to waḥdat al-wujūd. Meanwhile they talk about Towhid-e Sefati, but without any clarifying it.
They claim that they do not believe in dualism. In their view some sentences about dualism in Gathas should be interpreted. Never the less their interpretation is consistent and they must interpret it again
