Skanda Purana — Kashi Khanda, Shloka 80
योभूच्चटचटाशब्दः स्फुटतो भूमिभागतः । तच्छब्दाद्व्यसृजद्वेधाः समाधिं क्रमतो वशी
yobhūccaṭacaṭāśabdaḥ sphuṭato bhūmibhāgataḥ | tacchabdādvyasṛjadvedhāḥ samādhiṃ kramato vaśī
Alors s’éleva, distinct, un son « caṭa-caṭa » depuis une région de la terre ; et, à ce son, le Créateur, maître de lui-même, se délia du samādhi pas à pas.
Skanda (deduced: Kāśīkhaṇḍa commonly Skanda → Agastya)
Tirtha: Kāśī
Type: kshetra
Scene: Brahmā seated in deep samādhi upon a lotus-like seat; from the earth-region ahead arises a crisp ‘caṭa-caṭa’ vibration, shown as rippling lines or sparks; Brahmā gradually opens from trance, the atmosphere still and cosmic.
FAQs
Inner awakening can begin from nāda (subtle sound), drawing the mind out of absorption into conscious insight.
The broader context is Kāśī (Vārāṇasī) in the Kāśīkhaṇḍa, where sound (nāda) and liberation-teachings are celebrated.
None explicitly; the verse describes a meditative-cosmic event (samādhi and nāda) rather than a concrete rite.
