The last 9 days of Navaratri, we sung with Swami Vishwananda every night this sweet prayer to the Divine Mother:
A Prayer to Mother Divine, composed by Adi Shankaracharya in a high state of devotion and Divine bliss to uplift the devotees. Swamiji told us, that Adi Shankaracharya sung it to the Divine Mother und she started to cry.
