-- न्यस्ताक्षरामक्षरभूमिकायाम् Rāmāyaṇa18. 46 अ-क्षर--न्यास writing
-- rebus logo-semantics of metalwork words
Vātsyāyana refers to mleccchita vikalpa 'writing cipher by mleccha, copper workers) as one of the 64 fine arts learnt by youth); two other arts related to language are: अक्षरः-मुष्टिका 'finger-speech', speaking by means of finger-signs. देश--भाषाf. jñānam ज्ञानम् knowledge,learning of the language or dialect of a country
The key component of the Indus Script Cipher is based on this देश--भाषा f. jñānam ज्ञानम् , i.e. knowledge of the dialects or spoken forms of literary words. The spoken forms constitute Meluhha or mleccha (so0-called mispronunciation) compared with literary style expressions of the same semantic content. The mleccha or meluhha spoken forms (or mispronunciations) are evident in hundreds of thousands of words of ancient Indian languages which constitute an Indian spraschbund or 'speech union'. These spoken forms of the अक्षर, hieroglyph or hypertexts in writing are read rebus in the vikalpa or rebus representations of similar sounding dialect words which signify wealth-accounting or metalwork catalogues of artisans and seafaring Meluhha merchants of Sarasvati Civilization. This is the reason why Vātsyāyana refers to the cipher or writing system as mlecchita vikalpa; mleccha 'n. copper' rebus: mleccha 'one who mispronounces or deploys ungrammatical expressions'; rebus: mleccha 'a person who lives by agriculture or by making weapons'. These semantics reinforce the Indus Script decipherment of over 8000 inscriptions as wealth-accounting ledgers of metalwork.
An example of अक्षर भूमिका 'tablet with writing' found at Harappa; a tablet is so-called because, the suffix - भूमिका in the expression signifies 'earth, ground, soil'; it is a terracotta or earthen tablet.
