The voice changes. It is no longer Krishna. It is no longer Arjuna. Sanjaya — the narrator, the witness — steps forward. Speaking to the blind king Dhritarashtra, he says: I heard this dialogue between Vasudeva and the great-souled Partha. It was wondrous. It made the hair on my body stand on end.
Sanjaya is the Gita's third presence — the one who watched and listened from afar, gifted with divine sight by the sage Vyasa. His testimony adds a layer of witness to the text. This is not just a teaching between teacher and student. It is a teaching that was overhead, treasured, and passed on.
The word 'romaharshanam' — causing the hair to stand on end — is Sanjaya's honest physical response. The Gita moved him. Not just intellectually. In his body. That is the mark of something that goes beyond philosophy into lived experience.
