Sikhi was built for householders. Guru Nanak rejected renunciation, settled at Kartarpur, and farmed while he taught, so the practice is designed to fit a working life. Its anchor is Amrit Vela, the still watch before dawn that Japji Sahib praises as the hour for truth's name: practitioners bathe, sit, and repeat Waheguru aloud, then in a whisper, then inwardly. A simrana, the Sikh rosary, commonly strung with 108 wool or iron beads, keeps the hands employed; how to chant Waheguru on it is simply one name per bead, unhurried, until the name has sounded 108 times and the circuit closes. Many pair the name with breath instead, Wahe as it enters, Guru as it leaves, and families often add a few pauris of Sukhmani Sahib or the morning nitnem alongside.
The rest of the day is the real arena. Guru Nanak's three pillars, kirat karo, naam japo, vand chhako: work honestly, repeat the naam, share what you earn, place simran inside the working day rather than apart from it, so devotees keep the name running while driving, cooking, or waiting between meetings, and let sangat and kirtan at the gurdwara re-tune it weekly. As for the benefits of chanting Waheguru, Sikh testimony centers on sukh, the settled peace to which Guru Arjan's Sukhmani Sahib returns line after line, along with fearlessness and evenness of temper. Where sleeplessness or anxiety has a clinical edge, simran walks beside treatment; it was never meant to stand in for it.
