The passage explains that in the past pilgrimages were undertaken when people became free of their worldly duties and wanted to take such a religious and pious journey in search of peace and knowledge. It used to be a sadhana, a way of communing with nature for the pilgrims of past. Pilgrims used to travel light, on foot and without the luxurious comfort of A.C hotel rooms and cars. The author says that pilgrimages, nowadays, have become more of a tourism opportunity where people go for picnics and fun.
