7. Maa Kaalratri

Worshipped on the 7th night

KALDATRI (Deadly Night) - Day 7

एकवेणी जपाकर्णपूर नग्ना खरास्थिता ।

लम्बोष्ठी कर्णिकाकर्णी तैलाभ्यक्तशरीरिणी ॥

वामपादोल्लसल्लोहलताकण्टकभूषणा ।

वर्धनमुर्धध्वजा कृष्णा कालरात्रिर्भयङ्करी ॥

Ma Kaladatri destroyer of all the demon entities,

Goddess Kaladatri fierce in her appearance truly,

Resembles a black-lotus - her form and body,

Whose laugh is terrific - bestow favour kindly. [7]

Dhyana mantram of Kaaldatri Navdurga is recited during the seventh day or Maha Saptami day during Navarathri. This mantra frees from misfortune and keeps him fit to face any challenge in life. On seventh day of Navratri, Yogis and other upasaks of Shakti concentrate their mind on Sahasrara Chakra, providing all siddhis and nidhis of universe. Kaaldatri puja makes the devotee free from material world and provides him with Ashta siddhis and Nava nidhis. With this puja, all his sins and obstacles are completely vanished.

Black skin with bountiful hair and 4 hands, 2 clutching a cleaver and a torch, while the remaining 2 are in the mudras of "giving" and "protecting". Her vahana is a faithful donkey. The destroyer of darkness and ignorance, Kaalratri is the seventh form of Nav-Durga meaning scourer of darkness; enemy of darkness.
