Bulleh Shah (1680 1757) (Punjabi: Shahmukhi:بلہے شاہ, Gurmukhi: ਬੁੱਲ੍ਹੇ ਸ਼ਾਹ}}), whose real name was Abdullah Shah , was a Punjabi Muslim Sufi poet, a humanist and philosopher.
Bulleh Shahs writings represent him as a humanist, someone providing solutions to the sociological problems of the world around him as he lives through it, describing the turbulence his motherland of Punjab is passing through, while concurrently searching for God. His poetry highlights his mystical spiritual voyage through the four stages of Sufism: Shariat (Path), Tariqat (Observance), Haqiqat (Truth) and Marfat (Union). The simplicity with which Bulleh Shah has been able to address the complex fundamental issues of life and humanity is a large part of his appeal. Thus, many people have put his kafis to music, from humble street-singers to renowned Sufi singers.
Bulleh Shahs popularity stretches uniformly across Hindus, Sikhs and Muslims, to the point that much of the written material about this philosopher is from Hindu and Sikh authors. His involvement with atheism did not sit well with the contemporary Muslims, as a result of which few biographies of him from Islamic sources exist.
