(or Ah-hi; Sanskrit) In ancient literature, Ahi can have many meanings depending upon usage: a snake, the serpent of the sky, the demon Vritra, a cloud, water, the sun, a traveller, the navel, lead, or (in arithmetic) the number eight. In Theosophy, the term Ah-hi is defined as “the serpents or dragons of wisdom,” a reference to realized Beings. In the Germanic Eddas, the Dragon is called Ahti.
