To ChrisJ: Om symbol

[emka]

Hello Chris,
What you call 30 is the symbol OM . ॐ
om, in Hinduism and other religions chiefly of India, is a sacred syllable that is considered to be the greatest of all the mantras, or sacred formulas. The syllable om is composed of the three sounds a-u-m which represent several important triads: the three worlds of earth, atmosphere, and heaven; thought, speech, and action; the three qualities of matter (goodness, passion, and darkness); and the three sacred Vedic scriptures (Rigveda, Yajurveda, and Samaveda). Thus, om mystically embodies the essence of the entire universe. It is uttered at the beginning and end of Hindu prayers, chants, and meditation and is also freely used in Buddhist and Jain ritual. From the 6th century, the written symbol designating the sound has been used to mark the beginning of a text in a manuscript or an inscription.
