Acquainted with its efficacy, Mother Gouri desired to learn it from
her Lord itself. But she forgot that all are not fit to receive, much less
aspire or practise it; only those endowed with Satthwic nature are eligible and
they alone can practise-repeating it fifty lacs of times with utmost
concentration. Lord Siva tried to convince of her ineligibility, as she
was of Rajasic nature out and out, and proud of her blooming beauty and
transitory charms. So under serving. When her adamancy reached the peak,
Lord Siva cursed her to turn ugly and wander on earth with every conceivable misery
attending on her. Her tearful prayer for redemption melted the All-merciful Lord
and directed her to go to Kalahasti for doing penance, and only then she would
be fit to receive that all potent mantra.
Accordingly, Mother Gowri descended; and with the timely guidance of Narada and
Vinayaka reached Kalahasti. Giving up her divine body, she started penance in
the earthly mortal frame. Before commencing, she bade her divine aspect Durga,
the most frightful to ward off all the untoward that might likely visit to
frustrate the attempt. Taking her seat on the mount nearby, he did what was bid.
