What shape is the letter a? In the Candronmīlana, the answer is not a metaphor — it is a table. This treatise on phonetics and divination assigns each Sanskrit vowel a color, a geometric form, and a place in the body, turning the alphabet into a map of the cosmos and of the person.
Vowels with colors and shapes
The manuscript contains a systematic yantra table: each vowel from a to aḥ is paired with a color and a figure.
a | ā | i | ī | u | ū | e | ai | o | au | aṃ | aḥ — vowels. White, white, yellow, yellow, variegated, variegated, red, red, smoky, smoky, black, white — colors. Circular, circular, elongated, elongated, triangular, triangular, quadrangular, quadrangular, vajra, vajra, fragmented, fragmented — shapes.
Every sound carries a visible form and a color, so that the phonetic system and the geometric one are the same system. To know the alphabet is to know a set of shapes and hues as much as a set of sounds.
The groups and their forms
The same scheme extends to the consonant groups (vargas), which the text describes in a second table and then in verse: the ka-group is elongated, the ca-group triangular, the ṭa-group a fragment, the ta-group wheel-shaped, and the pa-group like a sleeping snake.
The a-varga is said to be circular, the ka-varga elongated, the ca-varga triangular, and the ṭa-varga a fragment. The ta-varga is wheel-shaped, the pa-varga like a sleeping snake, and the ya-varga quadrangular, the śa-varga many-angled.
Group by group, the whole syllabary is assigned to forms — and through forms, to directions, colors, and the elemental structure of the world.
Sound mapped to the body
The Candronmīlana goes further, correlating the letters with the three doṣas and the bodily elements, and with birth and life outcomes. It is a system in which speech itself is cosmic: to utter a syllable is to sound one of the parts of the universe. For anyone who thinks of the alphabet as a neutral list of symbols, this manuscript is a bracing alternative — a world where every letter has a shape, a color, and a destiny.
