Guru Nanak was born in 1469 in the village of Talvandi, now known as Nankana Sahib in present-day Pakistan, into a Khatri Hindu family. His father, Kalyan Chand Das, commonly called Mehta Kalu, served as a village accountant or revenue official, and his mother, Mata Tripta, is remembered as gentle and devout. He had an elder sister, Bebe Nanaki, who is portrayed as deeply affectionate and spiritually perceptive, recognizing early in life that her younger brother possessed an unusual spiritual depth. This family setting provided both the conventional expectations of worldly responsibility and a subtle space in which his inner calling could emerge.

From a young age, Nanak’s temperament was markedly contemplative and introspective. Traditional accounts describe him as quiet and thoughtful, more drawn to solitude, reflection, and the company of holy people than to ordinary children’s games or pursuits. He showed a keen interest in religious and philosophical matters, often engaging in discussions that surprised adults with their insight. His inclination toward devotional hymns and the company of saints, alongside episodes of deep spiritual absorption, suggested a child whose inner life was already oriented toward the divine.

Nanak did receive some formal education, being sent to a village school to learn reading, writing, and the basics of accounting. Yet the narratives consistently portray him as questioning the value of learning that served only profit, status, or social prestige. He is said to have interpreted letters and numbers as symbols pointing to a higher reality, challenging his teachers by shifting attention from worldly utility to spiritual meaning. This same spirit of inquiry extended to religious instruction, where he would question orthodox views rather than simply memorize lessons, making him appear difficult to instruct by conventional standards.

A defining feature of his early years was a critical stance toward external ritual and social hierarchy. One well-known episode centers on his refusal to wear the sacred thread (janeu), where he argued that true worth lay not in an external symbol but in inner purity and virtue. In this and similar stories, he is depicted as challenging caste distinctions, empty formalism, and the sharp divisions between religious communities. Living in an environment shaped by both Hindu and Muslim influences, he interacted with pandits, mullahs, and ascetics, yet consistently emphasized the primacy of inner devotion over outward labels.

Accounts of his childhood also highlight a deep compassion and sense of equality. He is portrayed as showing kindness and respect to people of all backgrounds, including the poor and socially marginalized, and as being willing to give away food or clothing to those in need. This otherworldly orientation, however, created tension within his household. His father hoped he would take up practical work in trade or accounting, while Nanak remained largely indifferent to profit and status. In contrast, his sister Nanaki is remembered as a steady source of support, offering him understanding and shelter when others worried about his unconventional, spiritually absorbed way of life.
