Guru Nanak Dev Ji
Guru Nanak Dev Ji(15 April 1469 – 22 September 1539) was the founder of Sikhism and the first of the ten Sikh Gurus. His birth is celebrated worldwide as Guru Nanak Gurpurab on Kartik Pooranmashi, the full-moon day in the month of Katak, October–November.
Guru Ji travelled far and wide teaching people the message of one God who dwells in every one of His creations and constitutes the eternal Truth. He set up a unique spiritual, social, and political platform based on equality, fraternal love, goodness, and virtue.
Guru Nanak Dev Ji was born on 15 April 1469 at Rai Bhoi Ki Talwandi (present day Nankana Sahib, Punjab, Pakistan) near Lahore. His parents were Kalyan Chand Das Bedi, popularly shortened to Mehta Kalu, and Mata Tripta. His father was the local patwari (accountant) for crop revenue in the village of Talwandi. His parents were both Hindus and belonged to the merchant caste.
He had one sister, Bebe Nanaki, who was five years older than he was. In 1475 she married and moved to Sultanpur. Nanak was attached to his sister and followed her to Sultanpur to live with her and her husband, Jai Ram. At the age of around 16 years, Nanak started working under Daulat Khan Lodi, employer of Nanaki's husband. This was a formative time for Nanak, as the Puratan (traditional) Janam Sakhi suggests, and in his numerous allusions to governmental structure in his hymns, most likely gained at this time.
On 24 September 1487 Nanak married Mata Sulakkhani, daughter of Mūl Chand and Chando Rāṇī, in the town of Batala. The couple had two sons, Sri Chand (8 September 1494 – 13 January 1629) and Lakhmi Chand (12 February 1497 – 9 April 1555). Sri Chand received enlightenment from Guru Nanak's teachings and went on to become the founder of the Udasi sect.
Guru Nanak travelled extensively during his lifetime. Some modern accounts state that he visited Tibet, most of South Asia and Arabia starting in 1496, at age 27, when he left his family for a thirty-year period. These claims include Guru Nanak visiting the Mount Sumeru of Indian mythology, as well as Mecca, Baghdad, Achal Batala and Multan, in these places he debated religious ideas with competing groups. These stories became widely popular in the 19th and 20th century, and exist in many versions.
Guru Nanak appointed Bhai Lehna as the successor Guru, renaming him as Guru Angad, meaning "one’s very own" or "part of you". Shortly after proclaiming Bhai Lehna as his successor, Guru Nanak died on 22 September 1539 in Kartarpur, at the age of 70.
