Vyākaraṇa-saṅgraha: Pada–Vibhakti–Kāraka–Lakāra–Samāsa
अमौसशो द्वितीया स्यात्तत्कर्म क्रियते च यत् । द्वितीया कर्मणि प्रोक्तान्तरांतरेण संयुते ॥ ४ ॥
amausaśo dvitīyā syāttatkarma kriyate ca yat | dvitīyā karmaṇi proktāntarāṃtareṇa saṃyute || 4 ||

Indirectly: precise grammar prevents misreading of devotional instructions—helping a devotee understand correctly what is to be offered, worshipped, or sought.
Vyākaraṇa (grammar): the rule that dvitīyā-vibhakti marks the karma (object) of an action, even when the object is separated by intervening words.
