Guru Nanak (1469–1539) was the founder of Sikhism and the first of the ten Sikh Gurus. Born in the late 15th century in what is now Pakistan's Punjab, he emerged as one of the most influential religious reformers of medieval India — rejecting caste distinctions, ritualism, and idol worship, and preaching a monotheistic faith rooted in love, equality, and honest labour.
For UPSC, Guru Nanak is a core Medieval History figure, typically tested within the Bhakti Movement chapter and the social reform currents of medieval India.
Early Life
Guru Nanak was born on April 15, 1469 (celebrated as Guru Nanak Jayanti on Kartik Purnima — typically November) in the village of Talwandi (now called Nankana Sahib, in present-day Punjab, Pakistan).
Family:
- Father: Mehta Kalu (Kalyan Das) — a village accountant for the local landlord
- Mother: Mata Tripta
- Sister: Bibi Nanaki — his elder sister, one of his earliest spiritual admirers
- Wife: Mata Sulakhni (married around 1487)
- Sons: Sri Chand and Lakhmi Das
Early signs: Sikh tradition records several incidents from Nanak's childhood that indicated his spiritual inclination — his refusal to wear the sacred thread (janeu) at the Hindu coming-of-age ceremony, his contemplative behaviour, and his rejection of ritualism. The famous Sacha Sauda (True Bargain) incident — where young Nanak spent money given for trade on feeding hungry sadhus — is cited as an early expression of his philosophy of seva (service).
The Revelation and the Beginning of His Mission
Around the age of 30, while bathing in the Bein River near Sultanpur Lodhi, Nanak reportedly disappeared for three days. Upon his return, he is said to have uttered the famous declaration:
"Na koi Hindu, na koi Musalman" (There is no Hindu, there is no Muslim)
This statement captured the core of his mission — transcending religious divisions to emphasise a universal spiritual truth. He then began the udasis (long missionary journeys) that would define the next 25 years of his life.
The Four Udasis (Journeys)
Guru Nanak undertook four major udasis between approximately 1500 and 1524, covering vast distances across South Asia, West Asia, and beyond.
| Udasi | Direction | Key Places Visited |
|---|---|---|
| First | East | Haridwar, Varanasi, Gaya, Dhaka, Assam, Puri |
| Second | South | Southern India, Sri Lanka |
| Third | North | Kashmir, Ladakh, Tibet, Nepal |
| Fourth | West | Mecca, Medina, Baghdad, Kabul, Kandahar |
Companions: On most journeys, he was accompanied by Bhai Mardana (a Muslim rabab player) and Bhai Bala — symbolising interfaith harmony in his mission.
Famous episodes:
- At Haridwar: He threw water toward the west, saying he was watering his fields in Punjab — a parable about the futility of ritual practices (Hindus were throwing water east toward the sun for their ancestors)
- At Mecca: He reportedly slept with his feet pointing toward the Kaaba. When challenged, he asked the mullah to turn his feet in a direction where God was not present — teaching the omnipresence of the divine
- At Kurukshetra: He cooked meat on a pilgrimage day, challenging ritual food taboos
These stories (recorded in the Janamsakhis — traditional biographies) illustrate his pedagogical method: challenging religious orthodoxy through demonstration rather than abstract argument.
Core Teachings
Guru Nanak's teachings can be summarised in three principles and one foundational concept:
The Three Pillars
| Principle | Meaning |
|---|---|
| Naam Japna | Constant remembrance of God's name — meditation, devotion |
| Kirat Karni | Earning an honest living through one's own labour — rejection of asceticism and idle renunciation |
| Vand Chakna | Sharing what one earns with others — community welfare, charity |
The middle principle — Kirat Karni — was particularly radical. Most religious traditions of medieval India valued renunciation. Nanak insisted that householder life (grihastha) was fully compatible with spiritual realisation — you did not need to abandon family or work to attain God.
Monotheism: Ik Onkar
The first line of the Guru Granth Sahib (Sikh scripture) — composed by Nanak — is:
"Ek Onkar" (There is one God)
Guru Nanak rejected the concept of multiple gods and emphasised a single, formless (nirguna), all-pervading divine reality. This drew from both Hindu Upanishadic thought and Islamic monotheism but was not identical to either — it was a distinctly new religious synthesis.
Social Teachings
Rejection of caste: Nanak explicitly condemned caste discrimination. His community meals (langar) — where everyone sat together regardless of caste or religion — were a direct challenge to caste purity norms.
Equality of women: In an era when women were marginalised in religious life, Nanak asserted that women were equally capable of spiritual attainment. The famous verse: "From woman, man is born; within woman, man is conceived… Why call her bad, from whom kings are born?"
Rejection of ritualism: He criticised meaningless ritual — pilgrimages performed mechanically, idol worship without understanding, fasting without spiritual content.
Critique of religious hypocrisy: He attacked priests and mullahs who exploited laypeople for personal gain.
Kartarpur and the First Sikh Community
In his later years (c. 1521), Guru Nanak settled at Kartarpur on the banks of the Ravi river (in present-day Pakistan). Here he established the first Sikh community organised around his three pillars.
Key institutions he created:
- Sangat: Community of followers meeting for worship
- Langar: Community kitchen where all eat together
- Dharamsala: Place of worship (precursor of the Gurdwara)
Selection of Successor: The Birth of Sikh Guruship
Before his death in 1539, Guru Nanak chose his successor — not his sons, but his disciple Bhai Lehna (who became Guru Angad, the second Guru). This was a radical decision:
- It established the principle that spiritual merit, not hereditary succession, determined Guruship
- It created the institution of a succession of living Gurus (ultimately ten) — unique among world religions
- It ensured that the teachings would be carried forward and developed systematically
Guru Nanak and the Bhakti Movement
Nanak is traditionally placed within the Nirguna Bhakti tradition — which emphasised a formless God, alongside figures like Kabir, Ravidas, and Dadu Dayal.
Comparison with other Bhakti saints:
| Saint | Tradition | Key Emphasis |
|---|---|---|
| Guru Nanak | Nirguna (founder of Sikhism) | Monotheism, equality, householder spirituality |
| Kabir | Nirguna | Rejection of both Hindu and Muslim ritualism |
| Ravidas | Nirguna | Social equality, dignity of labour |
| Mirabai | Saguna (Krishna bhakti) | Personal devotion to a deified form |
| Tulsidas | Saguna (Rama bhakti) | Ramacharitamanas |
| Surdas | Saguna (Krishna bhakti) | Sursagar |
Nanak is unique among these figures because his teachings led to the creation of an entire religious tradition (Sikhism) with its own scripture, institutions, and distinct identity — rather than remaining within the Hindu or Islamic folds.
Legacy
Guru Granth Sahib: Nanak's hymns form the opening section (Japji Sahib) of the Sikh holy scripture. Approximately 974 hymns in the Guru Granth Sahib are attributed to him.
Sikh religion: Founded by Nanak, developed by his nine successors, and institutionalised by the tenth Guru (Guru Gobind Singh). Today Sikhs number ~30 million globally.
Social reform: The Sikh community's egalitarian practices — langar (free community kitchen) served to all, regardless of religion, caste, or status — trace directly to Nanak's foundational teachings.
Kartarpur Corridor: In 2019, India and Pakistan opened the Kartarpur Corridor, allowing Indian Sikh pilgrims visa-free access to Gurdwara Darbar Sahib Kartarpur (where Nanak spent his last years). This was one of the few positive India-Pakistan developments in recent decades.
