As the world marks Guru Nanak Jayanti 2025, this ABC Live feature traces how Guru Nanak Dev Ji’s timeless message of truth, equality, and compassion became the foundation of Sikhism and its living spirit today.

New Delhi (ABC Live): On 5 November 2025, India and the global Sikh community celebrate the 556th Prakash Parv of Guru Nanak Dev Ji, founder of Sikhism and messenger of equality, compassion, and truth.
Born in 1469 CE at Rai Bhoi di Talwandi (now Nankana Sahib, Pakistan), Guru Nanak lived in an era torn by invasion, empire, and inequality. The Delhi Sultanate was fading, the Mughal Empire was rising, and society was divided by caste, patriarchy, and ritualism.
Against this backdrop, one voice proclaimed a universal truth that would shape a new faith:

Ik Onkar — There is One Universal Creator.

From Revelation to Reform

As a child, Nanak questioned social barriers and religious dogma. While others performed rituals, he sought the living presence of God in every soul. His divine revelation at the Kali Bain river — that there is neither Hindu nor Muslim, only humanity — became the spiritual core of Sikhism.

For nearly twenty-five years, he journeyed across India, Tibet, Arabia, and Persia with his companion Bhai Mardana. These Udasis spread a message of unity and compassion through hymns, dialogue, and service.
Guru Nanak taught that divinity is not reached through ritual but through right living — remembering God (Naam Japna), working honestly (Kirat Karni), and sharing with others (Vand Chakna).

Building a Community of Equality

In 1522, he founded Kartarpur Sahib, a living model of social justice. There, he established the institutions of Sangat (collective congregation) and Langar (community kitchen), where everyone — regardless of faith, caste, or gender — ate together.
This simple act broke centuries of hierarchy and defined the social ethics of the Sikh religion: equality, dignity, and service.

Guru Nanak also defended women’s rights, asking,

“So kyon manda aakhiye jit jamme rajaan?”
(Why call her inferior, from whom kings are born?)

He restored spiritual dignity to women and to all those marginalised by birth or belief — a revolutionary vision centuries ahead of its time.

A Voice of Truth in an Age of Empire

Guru Nanak lived through Babur’s invasions that devastated North India. In his verses known as Babur Vani, he condemned tyranny and moral decay:

“Paap ki janj lae Kabla dhaya, jor kiya so haro bhaya.”
(Babur came from Kabul with the marriage party of sin and seized the bride of the land by force.)

Through these words, he became not only a saint but a social critic, confronting power with moral authority. His message transformed faith into resistance — a demand for justice grounded in compassion.

The Evolution of Sikh Faith

Before his passing in 1539 CE, Guru Nanak appointed Bhai Lehna as Guru Angad Dev Ji, ensuring continuity of leadership.
Successive Gurus built upon his vision:
Guru Angad created the Gurmukhi script, Guru Amar Das strengthened Langar and women’s participation, Guru Arjan Dev compiled the Adi Granth (1604), and Guru Gobind Singh founded the Khalsa (1699).
Thus, a philosophy born in humility matured into a disciplined spiritual community — blending devotion with courage, meditation with action.

The Timeless Relevance of Guru Nanak’s Teachings

Guru Nanak’s teachings form the basis of the Sikh religion because they united spiritual awareness with social responsibility.
He replaced ritual with righteousness, superstition with self-realisation, and fear with fearless love. His vision anticipated modern values — equality before law, dignity of labour, and freedom of conscience.

In today’s world — divided by religious conflict, economic inequality, and climate injustice — his teachings offer a moral blueprint for sustainable living and ethical governance.
Ik Onkar remains not only a theological truth but a principle for peaceful coexistence — a reminder that humanity shares one Creator and one destiny.

Conclusion — The Eternal Light of Truth

Guru Nanak Dev Ji’s message was not a rejection of religion but a restoration of its soul. He showed that spiritual awakening and social reform are inseparable. In a world obsessed with power, he preached humility; amid violence, he taught peace; among divisions, he revealed oneness.

His teachings formed the basis of the Sikh religion and a universal ethic for all humanity. Five centuries later, the light of Guru Nanak still shines — reminding us that the path to God begins with seeing the divine in each other.
