Answer:
Sikhism is an Indian religion founded by Guru Nanak (1469-1539), which developed in the context of the conflict between the doctrines of Hinduism and Islam during the sixteenth and seventeenth centuries.
The story of Sikhism begins with Nanak, a son of the ruling / warrior caste who lived between 1469-1538 and was born in northern India. He was influenced by holy men of the mystical branches Bhakti, of Hinduism, and Sufi, of Islam. Guru Nanak claimed to be a supreme being, and claimed that all religions used different names for the same deity, which he called Sat Nam ("True Name"). There are many similarities between Sikhism, Hinduism and Sufism (a branch of Islam). Sikh, for example, is the Hindu term for disciple. For the Sikhs, the reason for this is very simple: truth is not limited to one belief.
For Sikhism, God is eternal and formless, being impossible to grasp it in all its essence. He was the creator of the world and human beings and should be the target of devotion and love on the part of humans.
Sikhism teaches that human beings are separated from God because of the egocentrism that characterizes them. This egocentricity (haumai) causes human beings to remain trapped in the cycle of rebirth (samsara) and not achieve liberation, which in Sikhism is understood as union with God. Sikhs believe in karma, according to which positive actions generate positive results and enable a better life and spiritual progress; the practice of negative actions leads to unhappiness and to rebirth in forms considered inferior, as in the form of plant or of animal.
God reveals himself to men through his grace (Nadar), enabling them to attain salvation. The Divine gives himself to listen, revealing himself as a name. According to the teachings of Guru Nanak and the other gurus, only constant remembrance of the name (nam simaram) and the murmured repetition of the name (nam japam) allow humans to free themselves from the haumai.
