Aarti of Maa Kalratri -
कालरात्रि जय-जय-महाकाली.
काल के मुह से बचाने वाली.
दुष्ट संघारक नाम तुम्हारा.
महाचंडी तेरा अवतार.
पृथ्वी और आकाश पे सारा.
महाकाली है तेरा पसारा.
खड्ग खप्पर रखने वाली.
दुष्टों का लहू चखने वाली.
कलकत्ता स्थान तुम्हारा.
सब जगह देखूं तेरा नजारा.
सभी देवता सब नर-नारी.
गावें स्तुति सभी तुम्हारी.
रक्तदंता और अन्नपूर्णा.
कृपा करे तो कोई भी दुःख ना.
ना कोई चिंता रहे बीमारी.
ना कोई गम ना संकट भारी.
उस पर कभी कष्ट ना आवें.
महाकाली मां जिसे बचावे.
तू भी भक्त प्रेम से कह.
कालरात्रि मां तेरी जय.
