Ayurveda, Yoga and the Meaning of Om, Aum, Amen, Amin, Hum

“The holy Cosmic Sound of Aum (Om) or Amen is the witness of the manifested Divine Presence in all creation.

“Aum” of the Vedas became the sacred word “Hum” of the Tibetans, “Amin” of the Moslems, and “Amen” of the Egyptians, Greeks, Romans, Jews, and Christians. The meaning of “Amen” in Hebrew is “sure, faithful.”
