The
Devanagari is the alphabet of Sanscrit, Pali and Tibetan writing. It's inception is attributed to
Sarasvati. The texts as given on this site are more or less a phonetic transposition of the Devanagiri to the western alphabet, furthermore there are differences between Tibetan and Sanscrit. Several ways of spelling and pronunciation are possible, the most important is to always work with the mantra from the heart.
On this site I try to join the majority, and to be consistent within the site, and that is already difficult enough. Besides: if a minority persists long enough in its opinion, eventually that opinion will become dominant.
