Vajrâṅga said — "Leaving my Samâdhi at your behests I got up and found my wife beneath a tree standing horrified and crying in a very distressed condition I questioned her the cause of her grief and asked her to let me know what she wanted In reply she spoke out with great fear and altering accents that she was horrified by the cruel Indra who also beat her and subjected her to great troubles as one would do unto a helpless woman without a lord She also added that not being able to bear her sufferings she would give up her life unless blessed with a son who might drive away all her sufferings In order to fulfil her desires I am determined to practise further penances so that we be blessed with a son who would conquer the Devas'—10-15
