Maitreya Buddha's vows is to come at a time when people's
lifespan is uncountable (i.e 84000 years), height is very very tall
(i.e 160 feet high), very modern technology, no diseases, world
peace and union of four human planets, etc etc (if you wish to find
out more, I can pass you a book on the Sutra concerning Maitreya
Buddha attaining Buddhahood in English/Chinese). At that time, Pure
Land is established on Earth, why Pure Land?
In sutra, its stated that when Mind is pure, Land is pure. Meaning
those people at that time have pure minds, they do not commit
crimes, etc. And how? By purifying the human minds right now....
creating a Pure Land on Earth. At that time, more than 9 billion
people will attain enlightenment in each of the 3 famous Maitreya
Buddha's dharma discourse! And apart from that, many many billions
of people will all attain enlightenment afterwards...
I believe this is a very good read
