Let me tell you the sacred procedure for the grand offering of ten million oblations, a ritual renowned for bestowing all desired results. Among the sacrifices, the worship of the nine planets requires ten thousand offerings. Now, as revealed in the Purāṇas and Vedas, I shall describe its method. To the northeast of the sacrificial pit, a platform two spans wide is carefully prepared. Upon this, a square altar is established, facing north, surrounded by two embankments and matching in height and width. This altar is meant for installing the deities. Once the fire is kindled, the gods are invoked at this site. For the rites, twenty deities, along with twelve others, are installed. The planets worshipped are the Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rāhu, and Ketu—those celestial beings who bring welfare to the world. The arrangement of these planets is precise: the Sun is placed at the center; Mars to the south; Jupiter to the north; Mercury to the northeast; Venus to the east; the Moon to the southeast; Saturn to the west; Rāhu to the southwest; and Ketu to the northwest, each represented by white rice grains. Each planet is associated with its presiding deity: Śiva is the lord of the Sun, Umā of the Moon, Skanda of Mars, Hari of Mercury. Brahmā presides over Jupiter, Indra over Venus, Yama over Saturn, and Time over Rāhu. For Ketu, Citragupta is the presiding deity. Over all, the overlord deities—Agni, Waters, Earth, Viṣṇu, Indra, and the goddess Aindrī—are honored. Further, Prajāpati and the serpents, Brahmā as secondary deity, Vināyaka, Durgā, Vāyu, and Ākāśa are invoked with the sacred vyāhṛtis, as well as the Aśvinī Kumāras. In meditation, the devotee visualizes the Sun and Mars as red; the Moon and Venus as white; Mercury and Jupiter as tawny; Saturn and Rāhu as black; and Ketu and his group as smoky. Offerings are made with colored powders, garments, and flowers. Fragrant incense is placed above, and a beautiful canopy adorned with fruits and flowers is set up by the wise. Specific foods are offered to each planet: sweet rice to the Sun; clarified butter rice pudding to Soma; wheat cakes to Mars; milk rice to Mercury; curd rice to Jupiter; clarified butter rice to Indra; rice with pulses to Saturn; goat meat to Rāhu; colored rice to the comets. All are worshipped with various foods. To the northeast, an area is adorned with curd and unbroken grains, covered with mango leaves, and accompanied by fruits and pairs of garments. Here, a flawless pot, joined with five gems and five metals, is placed, and Varuṇa is installed within it. All rivers, beginning with the Ganges, the oceans, lakes, and the confluences of elephants, horses, roads, anthills, ponds, and cow pastures are invoked. Earth mixed with all medicinal waters is brought for the ritual bath of the sacrificer. May all oceans, rivers, lakes, and streams come for the sacrificer, bringing the destruction of sin. Thus, the immortals are invoked, and the offering begins with clarified butter, barley, rice, sesame, and other grains. The fuel sticks used are arka, palāśa, khadira, apāmārga, pippala, udumbara, śamī, dūrvā, and kuśa—used in order. For each, eight hundred or twenty-eight sticks are offered, mixed with honey, clarified butter, and curd. The wise prepare the fuel sticks for all rituals, each measuring a span, free from knots, branches, or leaves. For all the gods, the knower of the highest truth offers the fuel sticks separately, each accompanied by its own mantra. Further offerings of clarified butter and cooked food are made. After reciting mantras and making ten oblations, the ritual concludes with sacred utterances. The foremost Brahmins face north or east, and offerings of cooked food are made with mantras for each deity. Having properly offered these foods, the ritual proceeds. For the Sun, the offering is made with the mantra 'ākṛṣṇeti' by the twice-born. For Soma, the mantra 'āpyāyasveti' is used; for Earth, 'agnirmūrdhā divo mantra' is recited. For the son of Soma, 'agne vivasvaduṣasa' is uttered; for Brihaspati, 'paridīyā ratheneti' is considered proper. For Venus, 'śukraṃ te anyad' and also 'śanaiścarāya' are recited. Oblations are made with the mantra 'śaṃ no devī'. For Rāhu, the mantra 'kayā naścitra ābhuvat' is prescribed. For Ketu, a mantra is recited for the pacification of the Ketus. For Rudra, bali-homa is performed with 'ā vo rājeti'. For Umā, the mantras 'āpo hi ṣṭha' and 'syoneti' are used, and likewise for the Lord. For Viṣṇu, 'viṣṇoridaṃ viṣṇuriti' is chanted; for the Self-born Lord, 'tamīśeti'; for Indra, 'indram iddevatāteti', followed by oblations to Indra. For Yama, 'cāyaṃ gaur' is prescribed; for Kāla, 'brahma jajñānam' is praised. For Citragupta, 'ājñātam' is known; for Agni, 'agniṃ dūtaṃ vṛṇīmaha' is recited. For Varuṇa, 'ud uttamaṃ varuṇam' is prescribed for the waters; for the earth, 'bhūmeḥ pṛthivyantarikṣam' is recited. For Viṣṇu, 'sahasraśīrṣā puruṣa' is prescribed; for Śakra, 'indrāyendo marutvata' is praised. For the goddess, the rite is performed with 'uttānaparṇe subhage'; for Prajāpati, another homa is prescribed with 'prajāpatiḥ'. For serpents, 'namo 'stu sarpebhya' is recited; for Brahmā, 'eṣa brahmā ya ṛtvigbhya' is prescribed. Thus, with reverence and meticulous observance, the ritual unfolds, invoking the blessings of all the deities and planets, ensuring the fulfillment of desires and the destruction of sin.
