Within the revered Garuḍa Mahāpurāṇa, in the Pūrvakhaṇḍa’s Ācārakāṇḍa, there unfolds a sequence of sacred chapters, each illuminating profound practices and rituals for the seeker. The thirty-fifth chapter concludes with the explanation of the Gāyatrī Nyāsa, and the narrative continues, inviting the listener—addressed as the destroyer of Rudra’s sins—to learn the procedure of sandhyā, the daily ritual that purifies and uplifts. The ritual begins with the invocation of the praṇava (Om), the vyāhṛtis (the sacred utterances), and the Gāyatrī mantra, complete with its head. For the twice-born, it is taught that prāṇāyāma—the regulation of breath—burns away faults arising from mind, speech, and action. In the evening, one should approach the fire; in the morning, the sun; and during both, drink water as part of the purification. Using the Ṛc 'āpohiṣṭha', water and kuśa grass are employed to cleanse, for impurities of passion and darkness arise from waking, dreaming, and deep sleep. The ritual continues: with water lifted in the hand, one recites the appropriate mantra and pours it onto the ground. The sun is worshipped with the mantras 'udutyaṃ' and 'citram'. The devotee stands while reciting the morning prayers and sits for the evening prayers. Even sins committed over ten births, or repeated a hundred times in the past, can be cleansed by this practice. The Gāyatrī is said to become red, while Sāvitrī appears white. The placement of the sacred syllables is detailed: 'Om Bhūḥ' on the heart, 'Om Bhuvaḥ' on the head, and the wise place the second on the armor and on both eyes. At the hour of twilight, having placed these, one recites the mother of the Vedas. The threefold Gāyatrī embodies Brahmā, Viṣṇu, and Maheśvara, and through this practice, one is freed from all sin and attains the world of Brahmā. However, it is warned that the sun destroys those who neglect worship at twilight. The meter is the goddess Gāyatrī herself, and the supreme self is the deity invoked. Thus concludes the thirty-sixth chapter, 'The Procedure of Sandhyā', in the Ācāra section. The narrative then turns to the thirty-seventh chapter, where Gāyatrī is extolled as the supreme goddess, bestowing both enjoyment and liberation. The ritual of Gāyatrī is explained: reciting the trisandhya a hundred times, one dwelling in the world of Brahma, may drink water. With the mantra 'bhūḥ bhuvaḥ svaḥ', joined with twelve names, salutations are offered to Savitri and Sarasvati, to the mother of the Vedas, to Sankriti, to Brahmani, and to Kaushiki, in proper order. Offerings in the fire follow, with the proper tone—fuel, clarified butter, and oblation—performed for the attainment of righteousness, desire, and other goals. As prescribed, the mantra should be recited a hundred thousand times, using milk, roots, fruits, and arsha. The goddess is described as born on the northern peak, dwelling upon earth or mountain. Thus ends the thirty-seventh chapter, 'The Explanation of the Gayatri Practice'. The story advances to the thirty-eighth chapter, beginning with the worship of Durga at the start of the ninth day, using the mantra 'hrīṃ durge rakṣiṇī'. The devotee prays: “With this offering and gift, grant me all desires.” Durga is invoked as Mangala, Vijaya, Lakshmi, Shiva, and Narayani, in order, and her form is described—eighteen arms, shield, bell, mirror, forefinger, shakti, club, spear, skull, arrow, and goad. The mantra and recitation for the glorious Bhagavati are declared. The invocation to Chamunda is vivid and awe-inspiring: homage to the blessed goddess dwelling in the cremation ground, holding a skull, mounted upon a great spirit, surrounded by mighty vehicles, attended by hosts, with a great mouth and many arms, adorned with bells, drums, and anklets, laughing loudly, making shrill sounds, filled with all kinds of noises. Her form is fierce—covered with elephant hide, smeared with blood and flesh, tongue moving, terrifying teeth, shining like lightning, fierce-eyed, flickering tongue, frowning face, seated on a Karabhadra throne, adorned with a garland of skulls, crowned with matted hair and the moon, causing darkness, destroyer of obstacles. The mantra commands: accomplish this work, do it quickly, move, stir, lover of blood, flesh, and wine, strike, crush, cut, kill, repeat, body of thunderbolt, accomplish even against the wicked or not wicked in the three worlds, possessed or not possessed. The goddess is invoked to enter, advance, dance, bind, leap, burn, cook, seize, enter the circle, and act without delay, by the truth of Brahma, Vishnu, the sages, and Rudra. Her forms are strange, wrapped in black serpents, lips hanging, monstrous face, tawny matted hair. The mantra calls upon Brahmani, Maheshvari, Kaumari, Varahi, Aindri, Chamunda, Vaishnavi, Himavat-dweller, Kailasa-rider—each to come, to cut, blaze, break, drop, shake, seize, bind, burn, cook, pierce, strike, hit, cut, bite, fix, seize, and reveal gestures, bursting forth with power. The invocation continues: Chamunda, roaring in anger, causing destruction of demons, moving in the sky, binding with the noose, staying, entering the circle, binding mouth, eyes, heart, hands, feet, all wicked spirits, the directions, above and below, with ashes, water, clay, or mustard seeds, commanding Chamunda to enter, drop, seize, bind, and act with ferocity. The mantra is a garland of one hundred and eight syllables, meant for recitation. With great flesh and triple sweetness, one should worship each syllable of the one hundred and eight thousand. Great flesh, triple sweetness, or otherwise, is suitable for all rituals. Thus, these chapters of the Garuḍa Mahāpurāṇa reveal the sacred procedures and the powerful invocations, guiding the devotee through purification, worship, and the attainment of both worldly and spiritual goals, honoring the divine with reverence and awe.
