Skandapurana 16.88

Īśvara said: / Then he should proceed, O great goddess, to Nīlarudra, the second, / situated to the north of Bhūteśa at a distance of sixteen bows; // 1

the great liṅga worshipped by gaṇas and gandharvas, O great goddess. / Having bathed it according to the prescribed rite, he should worship it with the Īśa mantra. // 2

Self-controlled and properly collected, with collections of white and blue water-lilies, / having circumambulated it, he should worship it with prostration. // 3

Having done so, O goddess, a man obtains the fruit of a Rājasūya sacrifice. / A bull should be given right there by those desiring the full fruit of the pilgrimage. // 4

In ancient times, a Daitya resembling blue collyrium, named Antaka, was slain; / because he made his women weep, he is known as Nīlarudra. // 5

His sin-destroying glory has been proclaimed in brief; / it is to be attained by those endowed with complete faith, and heard by those eager for his darśana. // 6
