Yoga Siddhi and Amba sing in a very groovy way, the last verse of the Gajananam during a Yoga Vidya satsang. The divine mother Narayani would like to serve all beings. She is the female aspect of Vishnu. You can find the text for this Kirtan in the Yoga Vidya Kirtan Songbook as No. 603: Om Sarva Mangala Mangalya Shive Sarvartha Sadhike Sharanye Tryambake Gauri Narayani Namostute
