Īśvara spoke, describing the sacred procedure of preparing the fire-altar for a holy rite. One should approach the fire-house with a composed mind, carrying the vessel for arghya, and, with divine vision, set out all the implements needed for the sacrifice. Facing north, the altar is to be carefully inspected; one must sprinkle and strike it with kuśa grass, recite the prescribed mantra, and anoint the altar with protective water. Next, with a sword, the pit for the fire is dug, cleared, filled, and leveled. Once again, it is sprinkled with protective water and pounded with an arrow. The area is then swept, smeared, and shaped with proper measurements, bound with three threads, and continually worshipped with protective water. Three lines of water are drawn: one to the east, one in front, and one below; or, if desired, their order may be reversed with sacred kusa grass and the Śiva weapon. With the mantra that renders the altar vajra-like, a fourfold path of darbha grass is laid out in the heart, and with the vessel mantra, the seat is widely arranged with focused intent. Vāgīśvarī is invoked there with the heart, and the Lord is worshipped. The sacred fire, properly supported, is placed upon a pure vessel. Any portion fit for carnivorous animals is discarded, and, after purification by inspection and other means, the bodily, lunar, and elemental fires are united into one. Uttering "om hūm" to awaken the consciousness of fire, it is installed with the fire seed; the fire, empowered by the samhita mantra, is transformed into nectar by the gesture of the cow. Shielded by the weapon mantra and veiled with spiritual armor, the worshipper circumambulates the altar to the right, carrying the worship thread. Within the domain of Vāgīśā’s womb, the Śiva seed is meditated upon, envisioned as being cast forth by Vāgīśvara. The priest, seated on the ground, casts this seed from his heart, facing himself, and gathers the group of inner seeds at his navel. With his heart, he performs the gathering of coverings, purification, and sipping rites. After worshipping the womb-fire and ensuring its protection with the arrow, he binds the bracelet of the goddess—born of the womb—on her tender hand and worships the fire with the Sadyojāta aspect for conception. With the heart mantra, three oblations are offered. To obtain a male child, worship is performed in the third month, on the left side. Three more oblations are given, each accompanied by drops of water on the head. In the sixth month, after worshipping the goddess of form, the parting of the hair ceremony is performed. Three oblations are offered with the topknot, using the topknot itself. Then the mouth is arranged, and the rites for opening and purifying the mouth are conducted. In the tenth month, as before, the birth and man-making rites are performed. The fire is kindled with darbha and other sacred materials, and the mother bathes to remove the impurities of childbirth. Meditating on the golden binding made for the goddess, worship is offered with the heart. To remove birth impurity immediately, water empowered by the weapon mantra is sprinkled. The ritual pot is struck with the external weapon and purified with armor; kusa grass is placed with the weapon outside the girdles, at the northern and eastern ends. Once placed, the wide covering is established with the heart. With the weapon mantra for the speakers, the three ends of the stalks are sanctified. Five kindling sticks, soaked in ghee, are offered at the ends and roots. With the heart, Brahmā, Śaṅkara, Viṣṇu, and Ananta are worshipped. Circumambulating the boundary in sequence with blades of dūrvā grass, each designated place is honored, proceeding from Indra and the other lords to each station in order. Facing the fire, worship is offered in each direction with the heart, seeking to ward off obstacles and protect the child. The Śaiva command is then announced. Taking the sruk and sruva, one proceeds, holding their mouths upward and downward, in order. After heating them in the fire, the root, middle, and tip of the darbha grass are touched. At the place touched by kuśa, one contemplates the self as knowledge and as Śiva. The three principles are placed in sequence with the syllables hāṃ, hīṃ, hūṃ, and saṃ. Śakti is placed in the sruci, Śambhu in the sruva, with the essence of the heart. Their necks are adorned with three threads and worshipped with flowers and similar offerings, then placed above the kuśa grass to the right. Cow’s ghee, purified by gazing and other means, is taken. Meditating on one’s own form as Brahman, the ghee is accepted. Above the altar, the ghee is revolved at the heart’s center within the domain of fire. Meditating on the form of Viṣṇu, the ghee is then placed in the domain of Īśāna. With the tip of kuśa grass, the ghee is offered with the syllable "svāhā" and the essence of the head—a drop is offered to Viṣṇu, and immediately after, to Rudra’s form. Contemplating the self, the offering is held at the navel and then floated; with darbha grass the size of a finger, touched with the tips of thumb and ring finger. Holding with both hands, facing the fire, the floating is performed with the weapon; likewise, from the heart and self, the floating is done in the same way. With darbha grass burned by the heart, it is purified by casting with the weapon; with another blazing darbha, the area is swept and ignited. With the weapon mantra, the darbha grass is burned in the fire again. After casting, darbha tied with a knot and finger-sized is taken and placed in the ghee. The two wings and the three channels—iḍā and others—are contemplated in the ghee. Three portions of ghee are taken with the sruva and offered in sequence. Thus, in the fire, a portion of ghee is offered, then the remaining ghee in order: "Om hāṃ, to Agni, svāhā; Om hāṃ, to Soma, svāhā; Om hāṃ, to Agni and Soma, svāhā." For the opening of the eyes, offerings are made to the three eyes of Agni. With the sruva filled with ghee, a fourth oblation is offered: "Om hāṃ, to Agni, for the sviṣṭakṛt, svāhā." With the six limbs, awakening is performed with the gesture of the cow. The ghee is covered with three threads and protected with the essence of the arrow. From the heart, drops of ghee are scattered, and purification is performed by sprinkling. The joining of the mouths and their unification is enacted: "Om hāṃ, to Sadyojāta, svāhā; Om hāṃ, to Vāmadeva, svāhā; Om hāṃ, to Aghora, svāhā; Om tatpuruṣa, svāhā; Om hāṃ, to Īśāna, svāhā." With each ghee offering, the joining of the mouths is performed, completing the sacred sequence as Īśvara prescribed.
