佛頂尊勝陀羅尼經教跡義記 2.94

2.94

唐云是我之義也。解曰：若自誦持，自稱名字；若為他人誦，稱彼人名字。為一切諸法皆從想生，念想連持稱名不間，一一獲福自利利他，故稱名字也。

In Chinese, it has the meaning of "me" [or "myself"]. The explanation states: If one recites and upholds it for oneself, one states one's own name; if one recites it on behalf of another, one states that person's name. Because all phenomena are produced from mental conceptualization, keeping thoughts in continuous succession and stating the name uninterruptedly, one obtains blessings in each instance to benefit both oneself and others; hence one states the name.
