सोपानम् १४: विवक्षा, अधिकार-प्रवाहः & सूत्र-वृत्तिः (Adhikāra Architecture & Semantic Intent)
Sopāna 14: Unlocking how governing Adhikāra sūtras project their authority over aphorisms to construct the complete executable Vṛtti for वर्तमाने लट् (३.२.१२३)
१. दर्शनम् — पं. ब्रह्मदत्त-जिज्ञासु-पद्धतिः (How Sūtras Inherit Power)
"अल्पाक्षरमसंदिग्धं सारवद्विश्वतोमुखम्। अस्तोभमनवद्यं च सूत्रं सूत्रविदो विदुः॥"
— विष्णुधर्मोत्तरपुराणम् (३.६.१) / स्कन्दपुराणम् (सूत्र-लक्षणम्)
"Those who understand sūtras know a true sūtra to be: having minimal syllables (अल्पाक्षरम्), free from doubt (असंदिग्धम्), containing core essence (सारवत्), universally applicable (विश्वतोमुखम्), devoid of meaningless filler (अस्तोभम्), and flawless (अनवद्यम्)."— Viṣṇudharmottara Purāṇa 3.6.1 / Skanda Purāṇa
Look at Sūtra 3.2.123: "वर्तमाने लट्". In the text of the Aṣṭādhyāyī, it consists of only two words! How does the computer/human know that it means: "After a verbal root, in the sense of present time, in active voice, the affix Laṭ is introduced strictly to the right"?
१. अधिकारः (The Governing Umbrella)
In Pt. Brahmadatt Jijñāsu's analysis, an Adhikāra is a high-level jurisdiction canopy. It stations itself once (e.g. प्रत्ययः ३.१.१, परश्च ३.१.२, धातोः ३.१.९१) and governs thousands of rules underneath without needing to repeat those words.
२. अनुवृत्तिः (The Continuous River Flow)
Anuvṛtti is the phonetic river that carries specific words from previous rules into subsequent rules. Like an electrical bus or variable inheritance, downstream rules tap into earlier terms without redundant syntax.
