Well in general when you are referring to the Supreme Lord/Devi you use the word "Ya" as in the verse stated above and others out there in Sri Rudram for instance:
या तेरुद्र शिवा तनू-रघोराऽपापकाशिनी ।
तया नस्तनुवा शन्तमया गिरिशंताभिचाकशीहि ॥ १-३
Ya te Rudra Shiva tanura ghora papakashini
taya nastanuva shantamaya girishanta bhichakashihi
O Lord ...
