A keen tattoo enthusiast noticed an error in my Siddhaṃ Heart Sūtra Mantra, and so I've updated it, and replaced the appalling Tibetan with a pic of it done with a font (Tibetan Machine Uni if you're interested).

Also since I've just covered past-participles in Sanskrit I've updated my Heart Sūtra mantra notes on the mess that is exegesis of the word 'gate'. I wrote something related on my blog recently as well: Words in Mantras that End in -e.
