Maila, Yes, you are right. Lot of people believe that Siddartha Gautam was not the first Buddha, nor was he last. If I am right, our Baudha stupa was actually made in reverence to a Buddha who came even prior to Siddartha Gautam. This Buddha - Buddha of Compassion - was a hunter. While he was hunting in the woods, which now is Baudha, came across a female tiger with cubs. Due to sickness or injury, this mother tiger was unable to hunt. She was physically decaying due to lack of food. And her cubs were also dying because her body could not produce any milk. Having seen this, the hunter was so overwhelmed with compassion that he gradually cut off his own limbs and fed the mother tiger until he died. But the tigress and her cubs lived. With this ultimate act of compassion, he gained nirvana. Some have given that Buddha a name of Avolokeshwar or Chengrisi. But he is said to have come back as Siddartha Gautam, aka Shakya Muni. Before he died, Shakya Muni did pronounce his imminent rebirth. That happened 8 years after his death in a place which we now know as Afghanistan. A child is said to have been formed in a lotus. This child later became a great teacher like Shakya Muni. We know him by various names such as: Padmasambava (Lotus Born) or Guru Rimponche. He is said to have come to Farping, very near Kathmandu, to do his meditation. He formed numerous schools in India and Tibet. He is the Buddha who emphasized more on meditative power to gain nirvana and much credited in Vajrayana or Tibetan Budhism. Yes, the sutras say that there will be another Buddha who will come in future. That Buddha will be known as Maitreya.
