Several resources serve as critical or annotated editions of the Tantrāloka, though no single “definitive” version has yet emerged. Key offerings include:

1. Sanskrit Critical Text by Jaideva Singh
   – Two-volume set (Motilal Banarsidass, 1964/1980).
   – Presents a meticulously collated Sanskrit text alongside a lucid English translation and extensive notes.
   – Remains the go-to for many academics, despite some gaps in manuscript coverage.

2. Nirnaya-Sagar Press Edition (1921–22)
   – Edited by Pt. Harinarayana Apte and Pandit Giridhar Bhatt.
   – One of the earliest printed Sanskrit editions, later reprinted by Chowkhamba (1969).
   – Lacks a modern critical apparatus but still valuable for tracing textual variants.

3. Kashi Sanskrit Series (Chaukhambha Surbharati, 1975)
   – Edited by K. Narayan Shastri, this version includes copious footnotes pointing out alternate readings.
   – More user-friendly for students dipping their toes into Kashmir Śaiva philosophy.

4. Lakshmīmālinī Commentary (Mark Dyczkowski, 1992)
   – While focused on a single chapter, this annotated English translation showcases Dyczkowski’s rigorous manuscript comparisons.
   – Offers a taste of what a full critical edition might look like.

5. Muktabodha Digital Library Project
   – An ambitious, ongoing effort to digitize and collate all known Tantrāloka manuscripts.
   – A beta release in 2024 gave researchers high-res scans and preliminary variant charts—still rough around the edges but promising.

Recent buzz from the 2023 World Sanskrit Conference hinted that a multi-institutional team (including scholars from Pune and Berlin) is gearing up to publish a fresh critical edition, leveraging AI-assisted collation tools. Meanwhile, anyone wanting a deep dive can also tap into the Government of India’s Vani portal, which hosts several manuscript copies, though without full scholarly annotation.

All these editions underscore one point: studying Tantrāloka is a bit like piecing together a Himalayan jigsaw puzzle. The groundwork laid by early printers and mid-century scholars opened the door; now, digital projects and fresh academic energy are filling in the corners, one folio at a time.
