Unless the Tripundra mark is taken up according to the S’âstras, the Vaidik Karmas (works) or those performed according to the Smritis prove injurious; the good works whatsoever done by any man count for nothing; the holy words heard seem as if unheard and the study of the Vedas counted as if not studied.
The study of the Vedas, Sacrifices, Charities, asceticisms, vows and fastings of that man, who does not use the Tripundra, all become fruitless. Without using Bhasma (ashes) if one wants liberation, then that desire is equivalent to live after taking poison. There is no doubt in this. The Creator has not made the forehead vertically high nor round; but he has made it slightly slanting and curved fit to have the Tripundra. Making thus the forehead, the Creator wants, as it were, to inform everyone that every one ought to use Tripundra marks; the curved lines also are made visible for this purpose. Still the igorant illiterate man does not put up the Tripundra. Unless the Brâhmanas use the curved Tripundras, their meditation won't be successful; they will not have liberation, knowledge, nor their asceticism would bear any fruit. As the S’ûdras have no right in the study of the Vedas, so the Brâhmans have not any right to perform the worship of S’iva, etc., unless they use the Tripundras. First of all, facing eastward, and washing hands and feet, he ought to make a resolve and then he takes a bath of the ashes mentally, controlling his breath. Then taking the ashes of the Agnihotra sacrifice he is to put some ashes on his own head, uttering “Îs'âna” mantra. Then he is to recite the Purusa S’ûkta Mantra and apply ashes on his face; with the Aghora mantra on his chest; with the Vâmadeva mantra, on his anus; with Sadyojâta mantra on his legs; and with the mantra Om, he is to besmear his whole body with ashes. This is called the bath of fire by the Munis. So bring all the actions to a successful issue one is to take first of all this bath of fire. Washing his hands, then, he is to make Âchaman duly; and, according to the above-mentioned rules, he is to apply ashes on his forehead, heart, and all round the neck with the five mantras above-mentioned; or with each mantra he is to apply the Tripundras. Thus all works are fructified and he gets the right to do all the Vaidik actions. The S’ûdras, even, are not to use the ashes touched by the lowest classes. All the actions ordained by the S'âstras are to be done after being besmeared with ashes of the Agnihotra sacrifice; otherwise no action will bear any fruit. All his truth, purity, Japam, offering, oblations to the sacrifice, bathing in the holy place of pilgrimage, and worshipping the gods become useless, who does not hold Tripundra. No fear of disease, sins, famine, or robbers comes to the Brâhmins who use Tripundra and rosary of Rudrâksa and thus remain always pure. In the end, they get the Nirvâna liberation. During the time of Srâddhas (solemn obsequies performed in honour of the manes of deceased ancestors) the Brâhmins purify the rows where persons are fed; so much so that the Devas glorify them. One must use the Tripundra marks before one performs any Srâddha, Japam sacrifice, offering oblations or worshipping the Visvedevâs; then one gets deliverance from the jaws of death. O Nârada! I am now speaking further of the greatness in holding the Bhasma; listen.
Here ends the Twelfth Chapter of the Eleventh Book on the greatness in holding the Tripundra and Bhasma in the Mahâpurânam S’rî Mad Devî Bhâgavatam of 18,000 verses by Maharsi Veda Vyâsa.
