Guru Nanak was not content to remain a mystic. He undertook four long travels, called udasis, to spread his message far and wide, and to share his spiritual experiences with others. Bhai Mardana always accompanied the Guru during the missionary tours. During his four travels, Guru Nanak visited different religious places. He went to Kurukshetra, Haridwar, Joshi Math, Ratha Sahib, Gorakh Matta (Nanak Matta), Audhya, Prayag, Varanasi, Gaya, Patna, Dhubri and Gauhati in Assam, Dacca, Puri, Cuttock, Rameshwaram, Ceylon, Bidar, (...) Baroach, Somnath, Dwarka, Janagarh, Ujjain, Ajmer, Mathura, Pakpattan, Talwandi, Lahore, Sultanpur, Bilaspur, Rawalsar, Jawalaji, Spiti Vally, Tibet, Ladakh, Kargil, Amarnath, Srinagar, and Baramula. Guru Nanak also paid visits to Muslim holy places. He went to Mecca, Medina, Baghdad via Multan, Peshawar Sakhar, Son Miani, Hinglaj etc. Some accounts say that Guru Sahib reached Mecca by sea route. He also visited Syria, Turkey, and Tehran (Iran). From Tehran he set out on the caravan route and covered Kabul, Kandhar, and Jalalabad. The aim of his tours was to awaken the people, to realize the truth about God and his creation. He established a network of preaching centers of his philosophy, which were called “Manjis”. He appointed able and committed followers as their in-charges. The basic tenets of Guru Nanak's philosophy were wilfully conceived by people from all walks of life. Thus the seeds of Sikhism were sown all over India and abroad in a well-planned manner. (shrink)
