Sanskrit commentary on the Bhagavad Gītā (title unresolved)

What is actually verified

Scan 365 / printed page 338 of Bhuwaneshwar Nath Mishra “Madhav”, Rāma-bhakti-sāhitya meṃ Madhura Upāsanā (1957), states that additional works by Kāṣṭhajihvā Svāmī had also been found and describes one object as गीता-व्याख्या (संस्कृत). This is a descriptive identification, not a verified proper title. This verifies secondary bibliographic metadata, not a primary text. The canonical total is unknown.

Direct reinspection of the Chapter Eight contents independently reads गीता-व्याख्या (संस्कृत). This corroborates the description, not a proper title.

Bounded source search

Descriptive-title and author-variant searches, six Internet Archive metadata query families, public catalogue and manuscript-index searches, and saved local research produced 0 exact-work candidates. Search absence does not prove that the work is lost.

Generic Sanskrit Bhagavad Gītā commentaries, famous bhāṣyas, unrelated modern editions, and general notices of Kāṣṭhajihvā's Sanskrit and Hindi writings were quarantined because none identifies this exact commentary.

Precise gaps
