大唐西域記 1.98

1.98

行六百餘里，出都貨邏國境，至梵衍那國。

This country from east to west is 500 li or so, from west to south 300 li. The capital is 4 or 5 li in circuit. The soil is stony, the country a succession of hills. There are but few flowers or fruits, but plenty of beans and corn. The climate is wintry; the manner of the people hard and forbidding. There are some ten convents or so, and about 200 priests. They all belong to the school of the Sarvastivadas, which is a branch of the Little Vehicle.
On the south-east we enter the great Snowy Mountains. These mountains are high and the valleys deep; the precipices and hollows (crevasses) are very dangerous. The wind and snow keep on without intermission; the ice remains through the full summer; the snow-drifts fall into the valleys and block the roads. The mountain spirits and demons (demon sprites) send, in their rage, all sorts of calamities; robbers crossing the path of travellers kill them. Going with difficulty 600 li or so, we leave the country of Tukhara, and arrive at the kingdom of Fan-yen-na (Bamiyan).
