The Rehras Sahib is the evening prayer of the Sikhs. It is recited at the end of a working day. This Bani is a collection of hymns of five different Gurus. The Rehras as recorded in the Guru Granth Sahib Ji contains hymns of only Guru Nanak Dev, Guru Amar Das, Guru Ram Das and Guru Arjan Dev. The compositions of Guru Gobind Singh were added in Rehias Sahib in the late 19th century.
Guru Nanak (Punjabi: ਗੁਰੂ ਨਾਨਕ) is the founder of the religion of Sikhism and is the first of the ten Sikh Gurus, the eleventh guru being the living Guru, Guru Granth Sahib. Guru Nanak travelled far and wide teaching people the message of one God who dwells in every one of God's creations and constitutes the eternal Truth. He setup a unique spiritual, social, and political platform based on equality, fraternity love, goodness, and virtue.
Guru Nanak’s teachings can be found in the Sikh scripture, Guru Granth Sahib, as a vast collection of revelatory verses recorded in Gurmukhi.
Through popular tradition, Nanak’s teaching is understood to be practised in three ways: * Vaṇḍ Chakkō: Sharing with others, helping those with less who are in need * Kirat Karō: Earning/making a living honestly, without exploitation or fraud * Naam Japna: Meditating on God's name to control your evils to eliminate suffering and live a happy life.
