न त्याज्यं सर्ववर्णैश्च भस्मधारणमुत्तमम् । अन्यैरपि यथाजीवैस्सदेति शिवशासनम् ३८ ।
Śiva has ordained that the rite of wearing ashes shall not be eschewed by the people of any caste and outside the bounds of caste by other living beings.
Brahmins, Kshatriyas, Vaishyas, Shudras, and even those of mixed caste, women, widows, children, and those who have fallen into hypocrisy or falsehood, all are included in this category.
