MALDUR ATAI is a moon-shaped mechanical puzzle helping the monks to reach other dimensions in Nepalese temples in pre-Buddhist era. In these temples, the priest used to give a strange puzzle to his disciples. The disciples had to solve its riddle. By solving it the disciples were opening the hidden gate and withdrawing from the material labyrinth to the vision world. Only the re-encoded puzzle was found in the room of the mystic who had solved the riddle. The number of disciples was gradually diminishing until only one disciple who did not solve the riddle was left.
