what moves the world?

I was trying to get breakfast this morning in the dinning hall of my working place, and when I passed in front of the kitchen door, I saw this youngish woman working in front of a grill there.
The kitchen had no windows and was probably hot. And she was there seriously working grilling some food.....

And I thought "why does she work there?"....and an answer came to my head: "she might have a son and she wants the best for him and she works there for him......she was doing it because of love........"

Then I remember that I thought something similar the other day when I was going in a bus: "what makes this driver come day after day and do this mechanical repetitive job, day after day, year after year?.......and I remember that a similar idea came to my mind: "he might have a daughter or a couple of dauhgters....and he loves them....and so he kind of do this for some kind of love......but love nevertheless......"

And I was still waiting on the line to get breakfast and a weird idea, or rather a question, appeared in my mind: " is it possible that loves moves this world more than we imagined?"....

Suffering

I had finished last night shift, I had changed my clothes and I was walking out, when I crossed in a corridor a middle age lady on a bed, being pushed. Walking behind, a man, possibly a boyfriend or a husband. On her face there was a lot of suffering and grief.

And a question crossed my mind: what is the origin of all human suffering?.
Then I realized the Buddha had asked that question and answered it....but I did not remember his answer. Can we leave that question open, for as long as it takes, without taking answers from anybody?
