The Description of the Index/Summary of the Garuḍa
Purāṇa
गीतासारः फलोत्कीर्तिः पूर्वखंडोऽयमीरितः । अथास्यैवोत्तरे खंडे प्रेतकल्पः पुरोदितः ॥ २० ॥
gītāsāraḥ phalotkīrtiḥ pūrvakhaṃḍo'yamīritaḥ | athāsyaivottare khaṃḍe pretakalpaḥ puroditaḥ || 20 ||
Assim, a seção anterior foi descrita como contendo a essência da Gītā e a proclamação de seus frutos; e então, na seção posterior desta mesma obra, o Pretakalpa—o regulamento acerca dos falecidos—já foi exposto anteriormente (como foi dito).

It functions as a table-of-contents marker, stressing that the text includes (1) a distilled teaching like a Gītā-sāra with its promised fruits, and (2) practical dharma concerning the departed (Pretakalpa), showing that wisdom and rite-based duty are both preserved in the Purāṇa.
By highlighting “Gītā-sāra” and “phala-utkīrti,” the verse signals that devotional listening/recitation and internalizing the core teaching yields spiritual fruit—typical of Purāṇic bhakti pedagogy where hearing (śravaṇa) and remembrance (smaraṇa) are emphasized along with promised results.
Direct Vedāṅga instruction is not the focus; the practical takeaway is ritual-dharma orientation via Pretakalpa—i.e., procedural guidance for preta-related observances (connected to kalpa/ritual practice), rather than grammar (vyākaraṇa) or astrology (jyotiṣa) in this specific verse.
