Although it wasn´t a British colony anymore there were lots of Europeans travelling to India in the 1970s. They came with the ´Hippie trail`, a big movement of mostly young people in search for spirituality. The reasons why they came were several. On the one hand they wanted to leave the money-oriented European world, on the other they expected to find the spirituality. It was like a search for love, peace and yourself. Most of them had become fascinated by the Hindu religion and hoped to get inspiration from Hindu gurus.
This trail was caused by the Beatles in 1966 who got effected by Indian music and religion. Many young people wanted to follow their heros and live on their example. However, most of them failed. Instead of spirituality they found poverty and homelessness. Often they took drugs and suffered not only physically but also emotionally from cuture shock and illness. The narrator of Heat and Dust meets some of those people (Chid) and is confronted with their situations (e.g. the people she sees on the streets in her first diary entry).
