Guru Nanak in Guruvani has classified human being in two categories: Manmukh (Governed by their mind), Gurumukh (Governed by their spiritual guru). He beautifully explains the miseries faced by manmukh in a shabad (Adi Granth, Page 1028-30): असुर सघारण रामु हमारा || घटि घटि रमईआ रामु पिआरा || नाले अलखु न लखीऐ मुले गुरमुखि लिखु वीचारा हे || He says that my Ram (God) who is present and permeated in everything is the destroyer of demons of passions and abnormalities. The vision for seeing the unfathomable and invisible God can only be obtained with the help of His saints (Gurumukh). गुरमुखि साधु सरणि तुमारी || करि किरपा प्रभि पारि उतारी || अगनि पाणी सागरु अति गहरा गुरु सतिगुरु पारि उतारा हे || There is no argument in this matter as God has ordained that he can meet through His saints and it is only by His grace, one can meet a perfect master. The perfect master (Satguru) helps in crossing the path of fire of passions and deep sea coming in the way to God. मनमुख अंधुले सोझी नाही || आवहि जाहि मरहि मरि जाही || पूरबि लिखिआ लेखु न मिटई जम दरि अंधु खुआरा हे || Manmukh (slaves of their mind) contrary to Gurumukh suffers from the pain of rebirth and death. He suffers from pains and miseries in this world and also dishonour and punishments from Yamdoots (angels of death) इकि आवहि जवहि घरि वासु न पावहि || किरत के बाधे पाप कमावहि || अंधुले सोझी बूझ न काई लोभु बुरा अहंकारा हे || He remains imprisoned in eighty four lakh yonis taking birth and rebirth and accumulating sins due to passions of mind due to greed, ego and ignorance. He never finds his eternal home.: पिर बिनु किआ तिसु धन सिगारा || पर पिर राती खसमु विसारा | जिउ बेसुआ पूत बापु को कहीऐ तिउ फोकट कार विकारा हे || A lady who forsakes her husband and spends time with other persons is never happy. She is unable to enjoy her wealth and prosperity as other persons can betray and leave her any time. Similarly, the soul leaving the true love of Lord spending time in worldly activities and sensual pleasures always remains worried with fear and anxiety. Whom we should call the father of child of a prostitute? Similarly manmukh runs here and there in search of peace and happiness and forgets his real father and suffers on that count. प्रेत पिंजर महि दूख घनेरे || नरकि पचहि अगिअन अंधेरे || धरम राइ को बाकी लीजै जिनि हरि का नाम विसारा हे || Guru Nanak has compared this body with cage of ghost as mind lives inside the body. In this cage of ghost, the re are many miseries and sufferings. Human beings are suffering in fires of hells after committing innumerable sins. सूरजु तपै अगनि बिखु झाला || अपतु पसु मनमुखु बेताला || आसा मनसा कूडु कमावहि रोगु बुरा बुरिआरा हे || The soul burns in fires of hell. The mind loses its reputation and suffers from innumerable hopes and desires. मसतकि भारु कलर सिरि भिरा || किउ करि भवजलु लंघसि पारा || सतिगुरु बोहिथु आदि जुगादि राम नाम निसतारा हे || The head is heavy with load of karmas and is unable to cross the hurdle. Only, satguru can help in crossing of soul to from one ship to another. पुत्र कलत्र जगि हेतु पिआरा || माइया मोहु पसारिआ पासारा || जम के फ़ाहे सतिगुरि तोडे गुरुमुखि ततु बीचारा हे || The mind loves sons and wife but remained unsatisfied. Only satguru can help in breaking this jinx.
