4000 years ago, people of deep faith save all their earnings (perhaps a lifetime earnings)to present oneself to the Temple. It took them days of traveling, which could be by foot, camel or donkeys. He has to bring with him a sufficient amount of money or gold or precious thing to be converted to buy offerings, which is usually a sheep or a goat. He has to pay extra for taxes of that purpose. The animals then are given to the person in charge of offerings. In the 21st century, people save money to go on a most aspired pilgrimage. It couldn’t be just something extra from one’s earnings, it should be a part of someone’s savings. Some are luckier to have come at an easier terms. Pilgrimage is an offering to God for his bountiful blessings, a thanksgiving.
