Guru Nanak Dev, the founder of Sikhism, taught a philosophy of monotheism, emphasizing the belief in one God, who is eternal, formless, and beyond human understanding. His teachings centered around the importance of meditation, devotion, and righteous living. Guru Nanak advocated for the internal realization of God, focusing on Naam Simran (the repetition of God's name) as the primary means to connect with the divine.
Guru Nanak rejected the caste system and emphasized the equality of all people, regardless of their social status, gender, or religious background. He promoted the idea of Seva (selfless service) as an essential part of spiritual practice. According to Guru Nanak, serving humanity was as important as devotion to God.
Guru Nanak also criticized the ritualistic practices of both Hinduism and Islam, calling for a direct, personal relationship with God. His teachings promoted peace, love, and tolerance, emphasizing that all religions are paths to the same ultimate truth. Guru Nanak encouraged his followers to live honest lives, earn a living through hard work, and share their wealth with others.
The key principles of Guru Nanak's teachings are encapsulated in the *Three Pillars*:
1. Naam Japna – Remembering God's name.
2. Kirat Karni – Earning an honest living.
3. Vand Chakna – Sharing with others.
These teachings laid the foundation for Sikhism and continue to guide Sikhs worldwide.
