Sorry ImI for interrupt, what I knew that the BUDDHA is BUDDHA that means he got NIRVANA and does not need to reborn again. Yes, Siddhartha was born before in different faces and different names to become a BUDDHA. Now, the another BUDDHA(not a same Buddha whom we worship) is comming in near future name is MAITRIYA to make our world Peace and Better, lets try to live till he born...... Peace
