The Gopatha Brahmana is the sole extant Brahmana text of the Atharvaveda, traditionally attributed to the sage Atharvan. It serves as a liturgical manual that explains the ritual application of Atharvavedic mantras, particularly those used in domestic rites (gṛhya) and magical practices (abhicāra). The text is divided into two parts: the Pūrva-brāhmaṇa (first section) and the Uttara-brāhmaṇa (later section), which together provide detailed instructions for ceremonies such as the installation of the sacred fire (agnyādheya), the new and full moon sacrifices (darśa-pūrṇamāsa), and various expiatory rites (prāyaścitta). According to the Gopatha Brahmana itself (1.1.1), the Atharvaveda is considered the fourth Veda, encompassing both auspicious (śāntika) and fierce (ābhicārika) rites.
The mantras are primarily addressed to deities like Agni, Indra, Varuṇa, and the Aśvins, but also to personified forces such as Fever (Takman) and Poison (Viṣa) for healing and protection. The beej-aksharas (seed syllables) found in these mantras, such as 'hūṃ' and 'phāṭ', are used for invoking protective energies and warding off evil. The Gopatha Brahmana emphasizes the power of correct pronunciation (svara) and ritual precision, as any error is believed to disrupt the efficacy of the rite. Traditionally, these mantras are chanted during sunrise or sunset, often in a consecrated space, with offerings of ghee and grains.
The recommended count varies: for healing, 108 repetitions (japa) are common, while for protection, a thousand repetitions (sahasra-japa) may be prescribed. Cautions include the need for ritual purity (śauca) and the guidance of a qualified priest (ācārya), as misuse of abhicāra mantras is said to bring negative karmic consequences. The Devi Mahatmya (Chapter 11) also references the protective power of Atharvavedic mantras, linking them to the goddess Durgā. Thus, the Gopatha Brahmana mantras are foundational for understanding the ritual and magical dimensions of the Atharvaveda, serving both worldly and spiritual purposes.
The Gopatha Brahmana mantras contain seed syllables such as 'hūṃ' and 'phāṭ', used for invoking protective energies and warding off evil.
