Sri Harmandir Sahib, also known as Sri Darbar Sahib or Golden Temple, (on account of its scenic beauty and golden coating for English speaking world), is named after Hari(God) the temple of God.The Sikhs all over the world, daily wish to pay visit to Sri Amritsar and to pay obeisance at Sri Harmandir Sahib in their Ardas.

Guru Arjan Sahib, the Fifth Nanak, conceived the idea of creating a central place of worship for the Sikhs and he himself designed the architecture of Sri Harmandir Sahib. Earlier the planning to excavate the holy tank (Amritsar or Amrit Sarovar ) was chalked out by Guru Amardas Sahib, the Third Nanak, but it was executed by Guru Ramdas Sahib under the supervision of Baba Budha ji. The land for the site was acquired by the earlier Guru Sahibs on payment or free of cost from the Zamindars (landlords) of native villages.

Digboi is a town and a town area committee in Tinsukia district in the north-eastern part of the state of Assam, India.The town's history begins in 1867 when a small group of men from the Assam Railway and Trading Co. found their elephants' legs soaked in black mud, that smelt somewhat like oil. The men began exploring more, and in 1889, the English started a small oil installation. India (and Asia) obtained its first refinery in Digboi in the year 1901. Various web sites offer variations on the elephant’s foot story, a consensus of which would be that engineers extending the Dibru-Sadiya railway line to Ledo for the Assam Railways and Trading Company (AR&TC) in 1882 were using elephants for haulage and noticed that the mud on one pachyderm’s feet smelled of oil. Retracing the trail of footprints, they found oil seeping to the surface. One of the engineers, the Englishman (not Canadian) Willie Leova Lake, was an ‘oil enthusiast’ and persuaded the company to drill a well.
