ते नाधीतं गुरोः सर्वं ते न सर्वमनुष्ठितम् । येन विप्रेण शिरसि त्रिपुंड्रं भस्मना कृतम् ३१ ।
If a brahmin wears the Tripuṇḍra with the ash on his forehead he must be considered as having learnt everything from the preceptor and as having performed every sacred rite.
With great devotion Brahmins and Kṣatriyas shall apply the holy ashes over such parts of the body as are prescribed by the rule repeating the mantra “Mānastoke” etc.
A Vaiśya shall apply the ashes repeating the Tryambaka[4] mantra and a Śūdra with the five-syllabled mantra[5]. Widows and other women shall do like the Śūdras.
