Meaning
Three words carry it, Hindi with a Punjabi turn: jai, meaning victory or glory; mata, mother; and di, the feminine possessive particle of Punjabi and Dogri, the equivalent of Hindi ki, so the cry unfolds as Mata di jai, the Mother's victory, and is the twin of the eastern Jai Mata Ki. Together they hail the Divine Mother, worshipped in the Shakta stream as Durga and, on that pilgrim route, as Vaishno Devi. Climbers on the mountain path call it to one another, so it serves as greeting, encouragement and prayer at once.
माँ की जय।
