Ezad

Meher Baba's most well-known prayer, known as the Master's Prayer or the Parvardigar Prayer, ends with the line:

"You are named Ezad, the only one worthy of worship."

Doing a search under "Ezad" reveals almost nothing, except references to Baba's prayer. Recently I posted the question of where this name of God originates on Facebook and got many replies, one in particular of immense value. Piecing together what I have learned, I will paraphrase.

Izad is a New Persian variation of Yazata (meaning "worthy of worship") and is a Zoroastrian name of God, signifying one of his qualities (i.e. worthy of worship). See etymology of yazata at Wikipedia.

I quote from the article here.

Yazata is the Avestan language word for a Zoroastrian concept. The word has a wide range of meanings but generally signifies (or is an epithet of) a divinity. The term literally means "worthy of worship" or "worthy of veneration". Reflecting the evolution of the idea of divine beings or angels in the Iranian world, it can be traced back to the earliest Old Iranian texts of the sacred book Avesta which are attributed to the prophet Zarathustra, founder of the religion Zoroastrianism, named after Zoroaster, another version of his name.

Yazata- is originally an Avestan language adjective derived from the verbal root yaz- "to worship, to honor, to venerate". From the same root comes Avestan yasna "worship, sacrifice, oblation, prayer". A yazata is accordingly "a being worthy of worship" or "a holy being".

As the stem form, yazata- has the inflected nominative forms yazatō, pl. yazatåŋhō. These forms reflect Proto-Iranian yazatah and pl. yazatāhah. In Middle Persian the term became yazad or yazd, pl. yazdān, continuing in New Persian as izad.

As I now understand it, Ezad is simply another way to spell Izad.

Kendra Crossen Burroughs explains:

The E is a way of indicating a short I. If diacritics were used, the long I would have a macron over it and the short I none. In the absence of diacritics, the e is used. 

As a matter of fact, Baba used the name "Ezad" in many prayers, that can be found collected here:
