अष्टोत्तरसहस्रेण पिबेद्ब्राह्मीरसं द्विजाः ऐहिकां लभते मेधां सर्वशास्त्रधरां शुभाम्
aṣṭottarasahasreṇa pibedbrāhmīrasaṃ dvijāḥ aihikāṃ labhate medhāṃ sarvaśāstradharāṃ śubhām
二度生まれの者(ドヴィジャ)は、ブラーフミーの汁(brāhmī-rasa)を千八(1008)の数にて飲むべきである。そうすれば、この世における知慧の光を得て、吉祥にして、あらゆるシャーストラを保持し得る。
Suta Goswami (narrating to the sages of Naimisharanya, within a didactic section on vrata/vidhi and merit)
It links disciplined practice (niyama) and sacred counting (1008/108-based japa-tally) with sharpening medhā, supporting accurate mantra-recitation and śāstra-understanding—key supports for proper Linga-pūjā and śaiva observance.
Implied is Shiva as Pati—the bestower of auspiciousness (śubha) and inner clarity—where refined intellect becomes a means to approach Shiva-tattva through correct understanding of śāstra and steady sādhana.
A medhya-rasāyana style discipline: drinking brāhmī-rasa with a sacred numerical observance (aṣṭottara-sahasra count), aligning bodily regimen with mantra-japa/niyama to strengthen dhāraṇā (retention) and learning.
