Which Layer Vitarka Mudra Belongs To

The word mudra covers three bodies of material that get printed together and are neither the same age nor the same kind of thing. The iconographic layer is a hand position that identifies a figure in sculpture and painting, readable from the early centuries CE onward. The textual layer is the mudras named in the hatha and tantric corpus, where a mudra is a whole bodily technique rather than a hand shape. The third is a twentieth century therapeutic literature of finger positions matched to elements and ailments, which borrows the vocabulary of the other two and is continuous with neither.

Vitarka Mudra belongs to the first layer. In the record it is primarily something a viewer reads off an image, and the gesture of exposition is iconographic and denotes teaching or argument in progress. Its close resemblance to the wheel-turning seal is the source of frequent misidentification in catalogues, and the two are distinguished by the position of the second hand rather than the first.

The consequence is that the surest evidence for this gesture is material rather than textual. Dated and provenanced sculpture gives a firm floor for when and where it was in use, which is a better class of evidence than most of the mudra literature can offer. Where a modern source attaches a therapeutic or energetic effect to it, that claim comes from the third layer and has been carried across; it is not part of what the iconography attests, and the two should not be read as one testimony.
