For those who are devoted to worship, the guidance is clear: those who are active should perform all acts of worship using a proper vessel. When conducting abhiṣeka—the sacred bathing—and making offerings, they should use rice-based food as the offering. When the worship concludes, the liṅga should be respectfully placed in a vessel or set aside in a separate, dedicated space. For those who are less active or unable to engage in elaborate rituals, it is appropriate to offer their own food in worship. Especially for such inactive devotees, the subtle liṅga becomes particularly significant. Their worship should be performed with vibhūti, the sacred ash, and this ash, too, should be offered to the liṅga. After the worship is complete, the liṅga should be placed upon the head in reverence. Vibhūti itself is said to be of three types, originating from the worldly fire, from the Vedic sacrificial fire, and from the fire of Shiva. Ash produced from the ordinary, worldly fire is used to purify various substances—whether made of clay, wood, metal, grains, or similar materials. The ash can also purify sesame and other seeds, cloth, and even items that have become stale. If anything has been defiled by contact with dogs or other impure things, purification by ash is recommended; one may apply the ash either with water or without, as the situation demands. Ash arising from the Vedic fire is to be worn at the conclusion of rituals. This ash, infused with mantras and generated from the sacred fire, is to be taken with ritual purity. By wearing such ash, the very essence of the ritual is established within the devotee. Using the aghora mantra, one should burn bilva wood to create the sacred Shiva fire. The ash produced from this fire is known as Shiva-fire ash. The process may begin with the dung of a tawny cow or simply with ordinary cow dung. Further, ashes produced by burning the wood of sacred trees—shami, asvattha, palasha, audumbara, vata, bilva, and others—within Shiva’s sacred fire, and properly purified, are truly called bhasma, the sacred ash born of Shiva’s fire. Alternatively, one may burn darbha grass or other suitable woods in the fire while reciting Shiva’s mantra, then purify the fresh ashes with a clean cloth and place them in a new vessel. This sacred ash is to be collected for the sake of spiritual brilliance and is deemed worthy of worship, for even Shiva himself followed this practice in ancient times. Just as a king takes for himself the best of what is useful in his realm, or as people consume the finest part of grains after burning away the chaff, or as the digestive fire in the belly nourishes the body with the essence of many foods, so too does Shiva, the Supreme Lord, take up the very essence of the manifest world after burning it under his control. Shiva, having thus burned the universe, smeared himself with its ash, symbolically taking the essence of all creation and placing it upon his own form. He established his own jewel-like essence throughout his body: his hair with the essence of space, his face with the essence of wind, his heart with the essence of fire, his skin with the essence of earth, his knees with the essence of water, and all his limbs in like manner. The tripundra—the three sacred lines of ash—is the distilled essence of Brahma, Vishnu, and Rudra, and Maheshvara, the Great Lord, wears it as a mark upon his forehead. Shiva sees all this as his own expansion, and thus, through this act, the entire essence of the universe is subdued by him. For this reason, he is called the subduer of all, just as the lion is the subduer among animals, for no beast is without fear of the lion. The syllables of Shiva’s name themselves carry deep meaning: ‘sha’ signifies happiness and bliss, ‘ma’ denotes the person or purusha, and ‘va’ stands for Shakti, immortality, and union. Thus, to worship Shiva truly, one should strive to make one’s own self Shiva in this way. Before smearing the sacred ash, one should carefully apply the tripundra in the highest manner, either with water for purification or without, at the time of worship. Whether it is day or night, whether the devotee is a woman or a man, for the purpose of worship, the tripundra of bhasma should be worn with water. Whoever, having adorned themselves with the tripundra of sacred ash and water, performs worship, surely attains the complete fruit of Shiva’s worship. One who wears the bhasma while reciting Shiva’s mantra becomes a true ascetic, a follower of Shiva, devoted solely to him. Such a devotee, observing the Shiva vow, need not be concerned with ritual impurities or birth pollution; he should always wear a mark of sacred ash on his forehead, applied with earth. Whether this mark is applied by one’s own hand or by the hand of the guru, it is the sign of a Shiva devotee. It is said to restrain the qualities of nature, and this is the true meaning of ‘guru’—the one who removes and dispels qualities such as passion and others. The Supreme Shiva, transcending all qualities, is assumed in the form of the guru. Having dispelled the three qualities, the guru first awakens Shiva within the disciple. For those disciples who trust him, the guru is thus called by that name. The wise recognize the guru’s body as the guru’s linga, and service to the guru is worship of that linga. The disciple listens and serves with body, mind, and speech, carrying out whatever the guru has instructed, whether it seems possible or impossible. With pure mind, the disciple accomplishes these tasks, even at the cost of his own life or wealth, and is thus fit for initiation. After giving all things, beginning with his own body, to the guru, the good disciple, having offered the first portion, may partake of food with the guru’s permission. The disciple is considered a son because of the sacred connection of discipleship; the tongue, linga, mantra, semen, ear, and womb are all consecrated in this way. Born as a son, the mantra-born disciple should worship the guru as father, for while the father brings the son into worldly existence, it is the guru who leads him across the ocean of worldly life. Knowing this difference, one should worship the guru as father, serving all the guru’s limbs—from feet to hair—with wealth and possessions acquired by oneself, honoring every part of the guru’s sacred being.
