Emblem as serpentine staff,
Hamsa, book, two branches with leaves and Sanskrit inscription-tamasoma jyotirgamaya which
is part of a prayer for enlightenment from brihat aranyako upanishad.
Meaning of the inscription is lead us from darkness to light
(Tamassu=darkness; Jyothi=light). The other two stanzas of this mantra are=asatoma
sadgamaya (from ignorance to truth) and mrithyorma amrutangamaya (and from death to
eternity). The medical emblem of two snakes intertwined around a staff originated from
Greek mythology. The staff of Aesculapius (God of medicine) stands for healing. Ancient
Greeks considered the staff as a badge of honor and noblemen carried a staff entwined with
garlands or ribbons. The garlands were later interpreted as snakes. Another reasons for
adding snake is that serpent represents wisdom. Christ adjured his disciples to be as wise
as snakes. The staff of Hermes (messenger of gods) has two snakes entwined around a staff
with wings. Aesculapius staff has a single snake and no wings.
