Vyākaraṇa-saṅgraha: Pada–Vibhakti–Kāraka–Lakāra–Samāsa
धातुस्तयोर्द्धर्मिभेदे सकर्मक उदाहृतः । गौणे कर्मणि द्रुह्यादेः प्रधाने नीहृकृष्वहाम् ॥ ८६ ॥
dhātustayorddharmibhede sakarmaka udāhṛtaḥ | gauṇe karmaṇi druhyādeḥ pradhāne nīhṛkṛṣvahām || 86 ||
கர்த்தா–கர்மம் இரண்டிற்கும் தர்மி-வேறுபாடு இருந்தால் வினையடி ‘சகர்மகம்’ எனக் கூறப்படுகிறது. கர்மம் துணையாக இருப்பின் ‘த்ருஹ்’ முதலியவை; கர்மம் முதன்மையாக இருப்பின் ‘நீ, ஹ்ரு, க்ருஷ், வஹ், ஹா’ முதலியவை.
Sanatkumara (teaching Narada; Vyakarana/Vedanga instruction context)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It frames sacred learning (Vedanga–Vyakarana) as disciplined discernment: understanding how action, agency, and object relate sharpens clarity in recitation, study, and right knowledge that supports Moksha-oriented practice.
Indirectly: precise grammar safeguards correct mantra and scripture transmission; accurate śabda (sound/word) supports steady śraddhā and right understanding, which strengthens Vishnu-centered devotion through error-free study and chanting.
Vyakarana: the criterion for calling a dhātu sakarmaka (transitive) based on kartṛ–karma role distinction, and the practical distinction between gauṇa (secondary) and pradhāna (primary) object with standard dhātu examples.
