The Great Epic of the Bhārata dynasty 13.15.51

13.15.51

vṛṇīṣvāṣṭau varānkṛṣṇa dātāsmi tava sattama |
brūhi yādavaśārdūla yānicchasi sudurlabhān || 51 ||

The innumerable Brahmanas there present, the deities and the Asuras, the Nagas, the Pisachas, the Pitris, the birds, diverse Rakshasas, diverse classes of ghosts and spirits, and all the great Rishis, then bowed down unto that great Deity. There then fell upon my head showers of celestial flowers possessed of great fragrance, and delicious winds blew on the spot. The puissant Sankara then, devoted to the good of the universe, looked at the goddess Uma and the lord of the celestials and myself also, and thus spoke unto me,--We know, O Krishna, that thou, O slayer of foes, art filled with the greatest devotion towards us. Do what is for thy good. My love and affection for thee is very great. Do thou ask for eight boons. I shall verily give them unto thee, O Krishna, O best of all persons, tell me what they are, O chief of the Yadavas. Name what thou wishest. However difficult of attainment they be, thou shalt have them still.'"
