ॐ इत्थं यदा-यदा बाधा दानवोत्था भविष्यति।
तदा तदावतीर्यां करिष्याम्यरिसंक्षयम् ॐ ।।

Devi Rajarajeshwari is a protector from natural and epidemic calamity, removal of delusional arrogance and she bestows all boons upon her devotees

सर्वमङ्गलमाङ्गल्ये शिवे सर्वार्थसाधिके ।
शरण्ये त्र्यम्बके गौरि नारायणि नमोऽस्तु ते ॥

CHANDI : In the Devi Mahatmyam, which literally translated as the glory of the Goddess, Devi is worshipped as Chandi. She is the embodiment of all power, abundance and intelligence. The embodiment of Durga Lakshmi and Saraswati. Hence this Devi mahatmyam is also known as Chandi. This has 700 mantras.

The Bhuvaneshwari Tantra says ” Just like the Vedas have no beginning , so is the Devi Mahatmyam considered.” This chandi homa in which the oblations are offered with all the mantras of the Devi mahatmyam, is hence equivalent to offering a homa with all the mantras of Rig Yajur and Sama Veda.
