Yagya →  – Yagya is by no means the standard form. All over wikipedia, the internet, scholarly publications and common usage, the Sanskrit form yajna is far and away the standard word. As a matter of fact, as a student of Buddhism and Jainism, of Hindu philosophy, of Indian languages and of Indian culture, I only ever met the form "yagya" in this page. I understand it can be a Hindi pronunciation of the word, but very obscure. I'm confounded by its presence... in fact, yagya's google hits are primarily of those of the band. '''''' smash!
