In Bhagvad Gita most of the slokas are in Anushtup chhandas (except a few which are in Trishtup chhandas)..
i.e., each verse of Gita consisting exactly of 32 letters, arranged in 4 quarters in a specific pattern of Laghus and Gurus..(except for a few verses in Trishtup meter.)
During the real verbal discussions of Bhagvad Gita did Lord Krishna and Arjun actually speak this way in direct speech? (32 letters arranged in 4 quarters with specific arrangement of Laghu and Guru syllables ?)
OR, did Sage Veda Vyas re-format their conversation in Anushtup meter for the purpose of indirect narration or record of Mahabharat ?
ie, I mean to ask if delivered words of Lord Krishna and Arjun actually verbatim ? or did Veda Vyas convert their dialogue into such a poetic meter?
For chandas information here is a rule for Anushtup meter
अनुष्टुप्छन्दसि चत्वारः पादाः भवन्ति प्रत्येकपादे च अष्ट > अक्षराणि।श्लोके षष्ठं गुरु ज्ञेयं सर्वत्र लघु पञ्चमम्।
द्विचतुष्पादयोर्ह्रस्वं सप्तमं दीर्घमन्ययोः॥
अस्य छन्दसः षष्ठम् अक्षरं गुरु पञ्चमम् च लघु। सप्तमम् अक्षरं प्रथमे तृतीये च पादे गुरु, द्विचतुष्पदयोः सप्तमम् अक्षरं लघु भवति। सप्तमम् अक्षरं यथाक्रमम् परिवर्तते, प्रथमपादे गुरु द्वितीयपादे लघु तृतियपादे गुरु चतुष्पादे लघु।

Anushtup meter has 4 quarters, each quarter has 8 letters, 6th letter of each quarter is Guru(deergha) and 5th letter Laghu (hraswa ). The 7th letter of 1st and 3rd quarters is a Guru and of 2nd and 4th quarters a Laghu. Thus the 7th letter is converted to (Guru, Laghu, Guru, Laghu) pattern in the 1,2,3,4 quarters respectively.
