The Supreme Buddha gained the knowledge to see how other beings travel in this cycle of samsara, one life to another, because of their good and bad actions. So what are the bad destinations ? Animal world, Titan world, Hell world and Ghost world. Do you know what the good destinations are? These are the human world, the 6 divine worlds and Brahma worlds. We had to know the safest life after death and act according to the Supreme Buddha’s teachings, to be born in those good destinations.
