Mbh 13.14.11f

On the other hand, all creatures bear the signs that mark Mahadeva and his spouse. Hence, all creatures must be regarded as belonging to Maheswara. All creatures of the feminine sex, have sprung from Uma's nature as their cause, and hence it is they bear the mark of femininity that distinguishes Uma; while all creatures that are masculine, having sprung from Siva, bear the masculine mark that distinguishes Siva. That person who says that there is, in the three worlds with their mobile and immobile creatures, any other cause than the Supreme Lord, and that which is not marked with the mark of either Mahadeva or his spouse should be regarded as very wretched and should not be counted among the creatures of the universe. Every being with the mark of the masculine sex should be known to be of Isana, while every being with the mark of the feminine sex should be known to be of Uma. This universe of mobile and immobile creatures is provided by two kinds of forms (viz., male and female). It is from Mahadeva that I wish to obtain boons. Failing in this, O Kausika, I would rather prefer dissolution itself. Go or remain, O Sakra, as thou, O slayer of Vala, desirest. I wish to have boons or curses from Mahadeva. No other deity shall I ever acknowledge, nor would I have from any other deity the fruition of all my wishes.--Having said these words unto the chief of the celestials, I became overwhelmed with grief at the thought of Mahadeva not having been gratified with me not withstanding my severe austerities. Within the twinkling of an eye, however, I saw the celestial elephant I had beheld before me transformed into a bull as white as a swan, or the Jasminum pubescens, or a stalk of the lotus or silver, or the ocean of milk. Of huge body, the hair of its tail was black and the hue of its eyes was tawny like that of honey. Its horns were hard as adamant and had the colour of gold. With their very sharp ends, whose hue was a mild red, the bull seemed to tear the Earth.
