We have nothing to drag in it by foreign empiric interpretation. Let it be understood as it is because it is just like the Sun. The Sun does not require to be helped by the light. So there is no need of understanding Bhagavad-gita by indirect interpretation. Kuruksetra is Kuruksetra. Dharmaksetra is Dharmaksetra. The Pandavas are Pandavas or the sons of Pandu and nobody else. The Pandavas & Kauravas not actually at the battlefield of Kuruksetra and the philosophy of Bhagavad-gita was told by the Supreme Personality of Godhead Sri Krishna.
I wish that your people may try to understand Bhagavad-gita in terms of its direct meaning. Let it not be unnecessarily misunderstood by the empiric speculative method. For making others of the vanity of so called learning without any living experience. Such academic erudity has nothing to do with the living reality.
