The Sikh Gurus stand as luminaries in the annals of Sikh history, revered for their profound spiritual insights, unwavering commitment to righteousness, and selfless service to humanity. By means of their sacred lives, teachings, and legacies, those first ones established a lively religion for Sikhs to follow into the way of truthfulness, equality, and worship of the heavens; as a result millions people received this way of life.Beginning with Guru Nanak Dev Ji, the founder of Sikhism, each Guru played a pivotal role in shaping the ethos and practices of the Sikh faith. Guru Nanak Dev ji, whose birthplace is Talwandi (this village is now known as Nanakana Sahib), took long journeys throughout geographical locations to spread the ideology of ikonkar (the notion of the formless and the omnipresent divine) together went with his followers and the concept of Simran (meditation on the divine name) and kar sema (selfless service).Guru Nanaks spiritual successor, Guru Angad Dev Ji, continued the mission of spreading Sikh teachings, furthering the practice of Naam Simran and promoting humility as a cornerstone of spiritual growth. Through his leadership, the Gurmukhi script was standardized, which allowed to set apart Sikh scripture as well as its conservation.Guru Angad Dev Jis emphasis on the importance of education and community welfare left an indelible mark on Sikh society.
