जपेदक्षरलक्षं वै चतुर्गुणितमादरात् नक्ताशी संयमी यश् च पौरश्चरणिकः स्मृतः
japedakṣaralakṣaṃ vai caturguṇitamādarāt naktāśī saṃyamī yaś ca pauraścaraṇikaḥ smṛtaḥ
ആദരത്തോടെ അക്ഷരലക്ഷത്തിന്റെ നാലിരട്ടി ജപം ചെയ്യണം. രാത്രിയിൽ മാത്രം ആഹാരം കഴിച്ച് സംയമത്തോടെ കഴിയുന്നവനെയാണ് പുരശ്ചരണികൻ എന്നു സ്മരിക്കുന്നത്.
Suta Goswami (narrating Shiva-puja disciplines to the sages of Naimisharanya)
It defines a core Shaiva preparatory discipline (puraścaraṇa) for Linga-centered mantra practice: a regulated japa-count done with reverence and supported by vows, making the worship fit to yield mantra-siddhi through Śiva’s grace.
Implied is Śiva as Pati—the bestower of mantra-siddhi—who responds not merely to quantity but to ādarā (reverence) and saṁyama (inner restraint), indicating that liberation-oriented power arises when the pashu’s impurities and bonds (pāśa) are attenuated through disciplined practice.
Puraścaraṇa for mantra-japa: repeating the mantra by akṣara-count up to four lakhs, with the naktāśī observance (night-only meal) and saṁyama (self-restraint), aligning japa with Shaiva vrata and Pashupata-style discipline.
