Guru Nanak Dev Ji embarked on four great Udasis — spiritual journeys — travelling across South Asia, the Middle East, and Central Asia. He engaged scholars, saints, and rulers of every faith, delivering the universal message of equality and devotion. His dialogues with Muslim qazis, Hindu pandits, and Sufi mystics are recorded as Janamsakhis and remain central to Sikh literary and devotional tradition.

Before becoming Guru, Bhai Lehna was a devout Hindu making an annual pilgrimage. After meeting Guru Nanak Dev Ji, he devoted himself entirely to Seva. Guru Nanak tested him many times — asking him to retrieve items from muddy water, carry heavy loads at night — and each time Bhai Lehna obeyed without question. Recognizing his selflessness, Guru Nanak named him his spiritual successor, giving him the name Angad — meaning ‘my own limb.’

When Emperor Akbar wished to meet Guru Amar Das Ji, he was informed that all visitors — regardless of rank — must first sit in Pangat and eat Langar before being received. The most powerful ruler in the world at that time sat cross-legged on the floor alongside farmers and labourers, sharing the same simple meal as an equal. Deeply moved, Akbar offered a land grant to the Langar. The Guru respectfully declined — accepting no outside donations for the community kitchen.

The city of Amritsar was built on land purchased at a fair price from local landowners, establishing Sikh precedent for honest transaction. Guru Ram Das Ji invited craftsmen, traders, and artisans from across the Punjab to settle around the Sarovar, creating a vibrant community. The site grew from a small pool into what would become one of the most visited spiritual destinations on earth.

When the Mughal Emperor Jahangir ordered Guru Arjan Dev Ji to remove Sikh and non-Sikh verses from the Adi Granth and convert to Islam, the Guru calmly refused. He was tortured for five days in the summer heat of Lahore — forced to sit on a heated iron plate while hot sand was poured over him — yet remained in a state of peaceful prayer throughout. His martyrdom in 1606 was the first in Sikh history and ignited the community’s resolve to defend their faith.

After being imprisoned in Gwalior Fort by Emperor Jahangir, Guru Hargobind Ji refused to accept his own release unless 52 Hindu princes imprisoned alongside him were also freed. The Emperor agreed, but stipulated that only those who could hold onto the Guru’s cloak as they passed through the narrow prison gate could leave. Guru Ji had a special cloak made with 52 strings — one for each prince — ensuring every prisoner walked free. He is remembered as Bandhi Chhor Divas — the Liberator.

Prince Dara Shikoh, the elder brother of Emperor Aurangzeb, fell gravely ill and no Mughal physician could cure him. Guru Har Rai Ji, known for his vast knowledge of herbal medicine, sent rare medicinal herbs from his own garden that restored the Prince to health — despite the Mughals having previously persecuted the Sikh Gurus. When asked why he would help an enemy, the Guru replied that a healer’s duty knows no borders of religion or politics.

A Brahmin named Lal Chand challenged the child Guru, claiming a young boy could not possibly possess divine wisdom. He brought a simple illiterate water-carrier named Chajju before the Guru as a test. Guru Har Krishan Ji placed his hand on Chajju’s head — and the labourer began reciting complex Sanskrit verses of the Gita with perfect accuracy. The Guru then passed away shortly after, having contracted smallpox while personally tending to those afflicted in Delhi’s epidemic. His last words pointed the Sangat to Baba Bakale.

A delegation of Kashmiri Pandits came to Guru Tegh Bahadur Ji in desperation, reporting that Emperor Aurangzeb was forcing mass conversion to Islam. The Guru’s young son, Gobind Rai, asked his father why the Pandits wept. When told they needed a great soul willing to sacrifice himself for their faith, the child declared, ‘There is no greater soul than you, Father.’ Guru Tegh Bahadur Ji proceeded to Delhi, was arrested, and was publicly beheaded on November 24, 1675 — giving his life not for his own faith, but to defend the right of others to practice theirs.

On Vaisakhi 1699 at Anandpur Sahib, Guru Gobind Singh Ji called the entire Sikh nation together and drew his sword, asking for one head. A man stepped forward. The Guru took him into a tent; the crowd heard a thud and the Guru emerged with a bloodied sword. He asked again — four more times, four more volunteers. The five became the Panj Pyare — the first members of the Khalsa. The ‘blood’ was revealed to be a goat’s. This founding act transformed the Sikh identity forever: every initiated Sikh became Singh (lion) or Kaur (princess), abolishing caste names in a single ceremony.
