the Highlands of Pamir

Alfons Paquet met Alexander de Salzmann in Istanbul 1921, Salzmann invited him to the Institute:

We met in the late evening and visited the Institute. It was named the Institute for the Harmonic Development of Man. Nothing less!...
I was introduced to the head of the school, a Caucasian, who had traveled for years to the mountain regions of Inner Asia, where he visited monasteries and studied the cults, dances and sciences of the monks. This man claimed that India wasn´t the "home of wonders", but instead he talked of the highlands of Pamir...
The fields of study of this Institute include lectures on asian religious myth, on rythym, on the law of octaves, on the science of numbers and what else is related to the Kabbalah and the magical crafts. They teach here a interpretation of the strange stone monuments, the dolmen...
Enthusiasm and boast, which accompany certain esoteric schools in the countries of the West, are far from them...

Alfons Paquet´s "Delphische Wanderung" was published in 1922.  Five pages of this book are dedicated to the visit of Gurdjieffs Institute in Istanbul, which Paquet visited only on one night in 1921.
