Truth (sach), a fundamental concept in Sikhism, has different meanings depending on its context. Truth stands for God, the Eternal Existence. It also means virtue and includes qualities such as humility, compassion, honesty, righteousness, justice, equality. Another meaning of Truth is something pure, holy, sacred, correct, and appropriate. It also means eternal happiness or bliss. Guru Nanak, in his hymns, enunciates about the Truth and the way to live a truthful life in harmony with the hukam (Divine Will). He declares that a holy congregation is a place for the realization of Truth. A disciple realizes the Truth by leading a virtuous life in the community’s service. The Guru articulates that the Truth cures all maladies and washes all sins from the disciple’s mind. The embellishment of Truth reveals itself in the excellent character and personality of the disciple. Such a person is called Sachiara (Truthful being) in Gurbani. Thus, Sachiara is a person who is imbued with the Eternal Truth (God). After achieving the Eternal Truth’s realization through reflection, contemplation, intuition and action, such a person ultimately merges in it. In this article, the concept of Sachiara, its various representations in Gurbani, its role in the Global Context and the way to be a Sachiara (Truthful being) is described.
