Śabda
Śabda (Skt., ‘sound’). Indian, and especially Hindu, recognition that ‘sound’ has levels of meaning, and is not mere noise: (i) sphoṭa, arising from the eternal, unmoving principle with illuminating power (śakti); (ii) nāda, perceptible only to a poet or ṛṣi; (iii) anāhata, potential (e.g. a thought) but not expressed; (iv) āhata, sound of all kinds, whether humans can hear it or not. Śabda has power in its own right, not just in speech, especially in mantras or in bells and drums: Śiva's drum (ḍamaru) manifests creation. Śabda-brahman is the ultimacy of sound devoid of attributes, the realization of Brahman. Initially, this was equated with the Vedas, but in the Upaniṣads it is Brahman.
