I knew the word "Sanskrit" and bon-ji (凡字). But I didn't know bon-ji meant Sanskrit words. Attached photo is a scroll of bonji. I used to think they are a variation of Kanji. My mother used the scroll in her ocha (tea ceremony) party. I don't remember what it says. I hope Jitu can help me decipher the words on the photo.
In the Japanese language, we use two sets of 54 simple letters beside kanji characters. One is hiragana, and the other is katakana. The first letter of the sets is "a," and the last, "um." I think this is the same as the beginning and ending of the Sanskrit words. In English, we spell it "Ohm." We say it "Aun."
