3.28.67

pitā te yācitaḥ pūrvaṃ mayā vai tvatkṛte'bale |
janako māmuvācetthaṃ paṇabandho mayā kṛtaḥ ||

Formerly I asked of you from your father, the king Janaka; but he then said, that he had laid a pledge, ‘Whoever will break the S’iva’s bow will marry my daughter.’ The Bhagvân Rudra is my Guru; hence I feared to break his bow, and therefore I was not present in your Svayamvara. But from that time my mind is always thinking of you and is in a state of bereavement for you.
