While reading nibandhas like Nirṇayasindhu & Smṛtitattva, it is found that the authors often quoted half-verses instead of the entire verse. For example, Kamalākara Bhaṭṭa quotes 'शरत्काले महापूजा क्रियते या च वार्षिकी।' only, omitting the next part (तस्यां ममैतन्माहात्म्यं श्रुत्वा भक्तिसमन्वितः॥) while writing about Navarāṭri. However this tactic can be easily abused as shown below in the next example
तच्छ्रुत्वा वचनं काव्यो जगाम त्वरितस्ततः । अपश्यद्दानवानां च पार्श्वे वाचस्पतिं तदा ॥ छद्मरूपधरं सौम्यं बोधयन्तं छलेन तान् । जैनं धर्मं कृतं स्वेन यज्ञनिन्दापरं तथा ॥ भो देवरिपवः सत्यं ब्रवीमि भवतां हितम् । अहिंसा परमो धर्मोऽहन्तव्या ह्याततायिनः ॥ द्विजैर्भोगरतैर्वेदे दर्शितं हिंसनं पशोः । जिह्वास्वादपरैः काममहिंसैव परा मता ॥ एवंविधानि वाक्यानि वेदशास्त्रपराणि च । ब्रुवाणं गुरुमाकर्ण्य विस्मितोऽसौ भृगोः सुतः ॥ चिन्तयामास मनसा मम द्वेष्यो गुरुः किल । वञ्चिताः किल धूर्तेन याज्या मे नात्र संशयः ॥ धिग्लोभं पापबीजं वै नरकद्वारमूर्जितम् । गुरुरप्यनृतं ब्रूते प्रेरितो येन पाप्मना ॥ प्रमाणं वचनं यस्य सोऽपि पाखण्डधारकः । गुरुः सुराणां सर्वेषां धर्मशास्त्रप्रवर्तकः ॥
On hearing those words, Kāvya i.e Śukra quickly returned back & saw the Master of Speech i.e Bṛhaspati there by the side of the Dānavas. In disguise (of Śukra), he was explaining to them the Jaina doctrines created by him, criticising the performance of yajña & other activities. On hearing lines alien to the Vedas & scriptures spoken by the Guru like, "Hear, O enemies of the Devas, the truth spoken by me for your welfare. Non-violence is the greatest virtue, even assassins shouldn't be killed. Injunctions for violence against animals are found in the Veda because the brāhmaṇas are addicted to sensual pleasures & want to satisfy the cravings of their tongues (implying that the Vedas aren't apauraṣeya but composed by brāhmaṇas), non-violence is the supreme virtue." the son of Bhṛgu was astonished. He thought to himself, "Surely this is Guru, my enemy. Undoubtedly, my yajamānas have been deceived by this cheat. Fie to greed, the seed of sin, the excellent gateway to hell, under whose influence even this Guru of sinful mind is speaking lies. He whose very statements are considered as authority, the promulgator of all religious texts, even that guru of the Suras have become the bearer of heresy." [Devībhāgavatapurāna Purāṇa:4:13:53-60]
So is there scriptural reference in support of glorifying even a half-verse ?
