Then there are people like me who think they come to learn, and the greatest lesson is of course love. But we have bodies to maintain and bodies of our families and animals to maintain, and the welfare of the country as a whole, nature to look after. In that process we learn to read and write and all the rest of it. And we learn an incredible lot of other things too, like astronomy and all the other sciences, in different portions according to what we are suited for.
The ones who like Buddha and many others become enlightened by sitting all day and night meditating, maybe they don't have to come back since they now know their true identities.
Then there are the likes of me, who still have a lot to learn and I am quite happy about that. It can be bothersome being a human, but it has its moments!
I don't mind coming back some more, although the world could soon be really awful. Maybe I could help in some way. That is what I would like to do if I am suited.
