Om Sarva Mangala Mangalye chanted by Shankari

Shankari chants during a Yoga Vidya Satsang the fifth verse of the Gajananam from the Dhyana Shlokas – in the Yoga Vidya Kirtan Songbook you'll find it as number 603:

Om Sarva Mangala Māngalye
Shive Sarvārtha Sādhike
Sharanye Tryambake Gauri
Nārāyani Namostute.

In English it means:

Worship the three-eyed mother Narayani.
She brings you bliss and fulfills all wishes of the seeker (both material and spiritual).
