Yenghe hatam

The Yenghe hatam is one of the four major mantras, and one of the most important prayers in Zoroastrianism. It is interpreted as a call to pray specifically to the Amesha Spentas, or generally to all Zoroastrian divinities.

Jointly with the Ahuna vairya, the Ashem vohu, and the Airyaman ishya; the Yenghe hatam forms the four mantras that enclose the Gathas in the Yasna and form the linguistically oldest part of the Avesta. It is furthermore found throughout many other parts of the Avesta, where it often marks the transition from one portion of the text to the next.

Text and interpretation
The Yenghe hatam reads as follows

A Pahlavi and Parsi Avestan translation would be:

Starting with the early exegesis of the Yenghe hatam in the Young Avestan period, the beings (hātąm) in the first line are generally interpreted to refer to the Amesha Spentas. However, some scholars have opined that it may refer to living men and women. The latter interpretation has become more influencal in modern interpretations of the mantra.

Source
The Yenghe hatam is generally considered to have been derived from Yasna 51.22, i.e., the 22nd verse of the Vohukhshathra Gatha. It reads as follows:

The main difference is to whom the worship is addressed. In the Gathic verse, the first line can be translated as "At whose sacrifice Ahura Mazda knows the best for me according to righteousness." In the Yenghe hatam, however, this is changed to "At whose of-the-beings [masc.] and of whom [fern. pl.] therefore Ahura Mazda knows the better for worship according to righteousness."

Language
The Yenghe hatam is part of a series of texts, which are linguistically distinct from the other parts of the Avesta. These texts are the four major mantras, the Gathas and the Yasna Haptanghaiti. The language in these texts is considered to be more archaic and is therefore referred to as Old Avestan vis-a-vis the Younger Avestan of the other texts. However, among these texts, the language of the Yenghe hatam has been labelled pseudo-Old-Avestan, due to a number of idiosyncracies.

One example is the relative pronoun yeŋ́hē (whose), which seems closer to the Young Avestan form yeŋ́he than the Old Avestan yehiiā as used in Y. 51.22. Such changes have been interpreted such that the mantra originated during the early Young Avestan period but was composed to make it appear more ancient.

Authorship
There is no consensus on the authorship of the Yenghe hatam. Tradition identifies Zarathustra as its authors and scholars like Gershevitch have affirmed that identification. On the other hand, some scholars like Boyce have pointed to the linguistic idiosyncracies of the mantra and concluded that it was composed by his early followers, who used the Gathic verse Y 51.22 as a model.

Translations
Like the other mantras, the Yenghe hatam can be diffucult to translate due to its brevity, complex grammatical forms and poetic ambiguity. As a result, a number of different translations exist. For examples, Skjaervo translates it as follows:
