Ahmet Kayhan Dede

Ahmet Kayhan Dede (1898, Pütürge, Malatya – August 3, 1998) was a Turkish Sufi master of the 20th century and an important figure in Islamic Mysticism.
Early years.
Ahmet Kayhan was born in the Aktarlar (Mako) village of Malatya Province, Turkey in early 1898, although the Turkish government lists his official year of birth as 1905. His father died when he was a child, and his mother in his early youth. For some years he stayed with an aunt.
Kayhan first met "Keko" (Ahmet Kaya Efendi), the man that would become his master, when he was only four or five years old. But his true discipleship began in his early twenties.
Adult life.
By 1922 Kayhan was living in Istanbul, making routine trips to the cities of Ankara and Malatya. In 1936 he relocated to Ankara, where he met Hajar, whom he would marry on March 25, 1937. His longtime master Ahmet Efendi died in 1944. Musa Kâzim Ağel, who had the same master as Ahmet Kaya, continued to teach until his own death in 1967. After this, it was Ahmet Kayhan's turn. He also gained the title "Dede", which actually means "Grandpa" and is appended to the name as an expression of loving respect as is customary towards elder relatives.
Ahmet Kayhan spent the rest of his life in Ankara, teaching and enlightening those around him and the many disciples that came to visit him from the 1960s on.
Line of descent.
Kayhan's chain of transmission is traced through Muhammad, his close associate Abu Bakr, Abdul-Qadir Gilani, Baha-ud-Din Naqshband Bukhari,
Ahmad Sirhindi, Abdullah Dehlewi, Khâlid-i Baghdâdî, Sheikh Samini, Osman Badruddin and Ahmet Kayhan Dede.
Vision of World Peace.
Kayhan foresaw that nuclear/biological/chemical (NBC) weapons of mass destruction (WMDs), but basically nuclear ones, would bring about the end of humanity. To avert this cataclysm, he issued calls to world peace in the 1980s and 90s. One of these, "An Invitation to Peace" (1987), won widespread acclaim, among others from the Russian premier Gorbachev, the Vatican, the French president, as well as both the president and prime minister of Israel.
Quotes.
″Allah (God), 
Let us bring peace to everywhere we go.
Let us be uniters rather than dividers. 
Let us bring love where there is hate settled in.
To the place where there is injury let us bring forgiveness and remedy.
Let us,
 Bring belief & faith where there is doubt settled in.
 Bring hope where there is no hope left.
 Bring light where there is darkness.
And let us (with your sincerely) allow to spread happiness where there is sadness.
Allah (God)!
Make me a person who hides other's faults instead of revealing
Make me a person who consoles (relieves) others instead of asking (needing) for one
Make me a person who is tolerating instead of being tolerated by others
Help us for not only ask to be loved but at the same time, wants to love.
Likewise rain, make me a person who don't hesitate to rain on everywhere equally, and bring liveness to everywhere it drops.
Make me a person,
Like the sun, who doesn't hesitate to light all the living things with it brightness.
Like a soil, who doesn't hesitate to share all the goods grown in him with everyone, even though it is being stepped on every time.
Let us join to the path that embraces ones who;
Have hands that give (share) instead of take,
Who is forgiven, because they learn to forgive,
Who born with - live for - and die with the belief of Allah (God),
and let us join the ones who reborn in the infinitive life.″
