1. I think it is very cool to know a 2000 year language, read ancient texts in the original and interpret them on your own rather than relying on other people's interpretation which often have religious and cultural biases.
2. It is beautiful because it has very precise rules. You can construct new words for things that didn't exist before (like computer) without violating the rules of the language.
I did not come up with it, others did. सङ्गणक (saṅgaṇaka - IAST transliteration). It is composed of three parts - a prefix, root verb and a suffix -
सम् + गण् + ण्वुल् = सङ्गणक
sam + gaṇ + ṇvul = saṅgaṇaka
The prefix imparts the meaning of doing well. The verb means to calculate. The suffix converts the verb into a noun that performs that action. It literally means an entity that is adept at calculating.
