Vyākaraṇa-saṅgraha: Pada–Vibhakti–Kāraka–Lakāra–Samāsa
स्मृत्यर्थकर्मणि तथा करोतेः प्रतियत्नके । हिंसार्थानां प्रयोगे च कृतिकर्मणि कर्तरि ॥ १६ ॥
smṛtyarthakarmaṇi tathā karoteḥ pratiyatnake | hiṃsārthānāṃ prayoge ca kṛtikarmaṇi kartari || 16 ||
Likewise, when an act is performed for the sake of remembrance (smṛty-artha), and when √kṛ “to do” carries the sense of deliberate exertion; and in usages that convey injury; and in actions brought about by an agent’s intentional undertaking—the agent (kartṛ) is understood as the locus and subject of the action.

It ties inner intention (prayatna) to the identification of the doer (kartṛ), implying that moral and spiritual responsibility in karma depends on deliberate agency, not merely on outward motion.
Indirectly, it clarifies that devotion is not just external ritual action—when acts are performed with conscious purpose (such as remembrance), the agent’s intentionality becomes central, aligning practice with mindful remembrance of the Divine.
Vyākaraṇa (grammar): it discusses how verbal usage and semantic conditions—remembrance-purpose, deliberate effort, and हिंसा-meaning expressions—govern the interpretation of agency (kartṛ) in an action.
