The name comes from the Sanskrit words Samrup (सामरुप) (سامروپ), meaning "congruence" or similar, and Rachna (रचना) (رچنا) meaning "creative work or design". The calligraphy is an attempt to use the two altogether different Devanagari and Nastaʿlīq script scripts, used by the same language Hindi -Urdu, in unison in such a manner that a picture of the word which is written is formed.This work is acknowledged by Indian and Pakistani print media also.
For example, the Hindustani word surahi (meaning "ewer" or "pitcher" in English) is written in Samrup Rachna calligraphy in Devanagri and Nastaʿlīq  scripts of Hindustani in a way that a picture of a ewer is formed.
In linguistics, languages which are written in two different scripts are called Synchronic digraphia. Hindustani is one such language. Samrup Rachna is also advocated by its inventor to help readers of Nastaʿlīq (Urdu) script to understand and learn the Devanagari (Hindi) script of the same language. This art is aimed at helping to dispel the existing religious association with the two scripts in the region of South Asia.
A unique linguistic cum calligraphic art book, Samrup Rachna – Calligraphic Expression of Apni Boli [Hindi-Urdu] was launched at the Mother Languages Literature Festival  held at the National Institute of Folk and Traditional Heritage ( Lok Virsa), Islamabad, in collaboration with USAID Agency and some other NGOs including Indus cultural Forum ( ICF) on 20 February 2016, by Dr. Syed Mohammed Anwer contains over 60 visual impressions of words with cultural connotations created out of the Hindi Devanagari script and the Urdu Nastaliq script. Beautifully presented in hardback form the book is as much a socio-political comment as a coffee table art book. Dr. Anwer learnt the Devanagari script from his mother. The two scripts are essentially “the same language, written differently” as explained by the artist’s mother. The purpose of the Book is to highlight the fact that association of any language or its script with any particular religion is a fundamental mistake. Language has no religion. The book can also be used as ‘easy-to-learn’ book for the ‘other’ script of Apni Boli [Hindi-Urdu] by its speakers.
The author of Samrup Rachna Calligraphic Expression of Apni Boli [hindi-Urdu] is an advocate of the Supreme Court of Pakistan and is a PhD on the topic of human rights from Punjab University. The polymath is also an active member of the civil society and has remained elected President of Islamabad Bar Association in 2013. He has also written books on human rights, women’s emancipation and other social issues.
