अनच्काक्षरसंयुक्तं कवर्गादिपञ्चकम् । ध्यायेद्वाच्यमसंस्पृष्टं ततो भवति भैरवः ॥
anackākṣarasaṃyuktaṃ kavargādipañcakam | dhyāyed vācyam asaṃspṛṣṭaṃ tato bhavati bhairavaḥ ||
The five groups of consonants from ka, united with the vowel 'a' without contact — meditating on the inexpressible and untouched, thus Bhairava arises.
Sixty-second technique. Phonetic meditation. Sanskrit consonants are organized in five groups (varga): ka, ca, ṭa, ta, pa. Each group has five letters sharing a point of articulation. United with the vowel ‘a’ without contact (anac — without nasal vowel).
Vācyam asaṃspṛṣṭam — what is said without being touched. The letters are pronounced but what they point to cannot be touched by language. The letters are the finger. The moon is the inexpressible.
Tato bhavati bhairavaḥ — thus Bhairava arises. Meditation on the structure of language reveals what lies beyond language. Sanskrit is considered devavāṇī — divine language — not by convention but because its phonetic structure maps the structure of consciousness.
