Molana-al-Moazam Hazrat Mir Ghotbeddin Mohammad Angha (Mohammad Angha), (born May 10, 1887, died September 22, 1962) ''' is the 40th Master of the Oveyssi school of Sufism.

Of the dignity in his supreme position in science and Sufism, it is said of this outstanding Arif of our era who is considered among the greatest in the history of Sufism:

"If it were not for our Lord Mohammad, son of Mir Abolfazl Angha, the reality of ma'rifa (cognition) would never have appeared in our era."

He was born in Tehran in 1887, and passed away in 1962, at the age of seventy-five. His Holy Shrine is located next to that of his father, Hazrat Jalaleddin Ali Mir Abolfazl Angha in ibn-Baveh, Iran.

From his youth he had an inward interest in developing human creative powers and mastering the natural sciences. As it stated in the introduction to his book, From Fetus to Paradise:

"Whenever I heard of a learned man, I hastily went to him with good faith and studied his speech very carefully, but I did not achieve my final goal. I could understand, however, that his ideas and deeds of those who served only appearances were based on imagination and imitation, and that a poor imitator would have no chance to research on his imitation, that a poor fellow would have to be satisfied with the unknown tomorrows."

Upon attaining the state of cognition, he wrote:

"I perceived that the Sufi's religion differs from others'. They are the lovers of God, and He is their religion. They do not waste their time and do not consider outside affairs as reality. They constantly relinquish worthless affairs, and they are steadfast in calamities and are released from the past."
