पार्वतीतपोवर्णनं नाम द्वाविंशोऽध्यायः
Parvati penance description Chapter 22
Brahma said (to Narada)
आहारे तयक्तपर्णाऽभूद्यस्माद्धिमवतः सुता |
तेन देवैरपर्णेति कथिता नामतः शिवा || 49 ||
Having become free from the diet of leaves, Shivaa, the daughter of Himavan was therefore called by the name Aparna by the Devas.
The supreme Goddess no longer ate anything, stood on one leg repeating the five-lettered mantra.
