Besides Nagarjuna cave there are some other cave of Buddha, Mahasiddhas.One of the famous story of the Buffalo Buddha: A long time ago when Acharya Nagarjuna was living in his cave, an idiot buffalo herdsman from Kathmandu became possessed by faith in the Master, and came to him frequently offering curd and milk, etc. Once when he asked Nagarjuna to come to town, the Master refused, saying, 'If you are able to meditate upon perfect reality, sit down here'. So he did as he was told, but obsessed by his work of guarding buffaloes he could think of nothing but buffaloes. 'Visualize yourself as a buffalo.' Instructed the Acharya. So he meditated in what today is called the Cave of the Buffalo Buddha, and after a while he actually became a buffalo. His horns struck the rock above him and the holes, which today are known as his horn-prints appeared. Then Nagarjuna told him to contemplate his body in its natural state of total relaxation. Meditating according, his body became as before and his senses became sharp and alert, so he was given initiation and precepts. After he had accomplished the aim of his mediation, it is said that he shot through the roof of the cave and went straight to the Dakini's Paradise.
