wht do u live for???

At times while driving I come across people on streets… recently 2 types of people intrigued me… one type was people who lived lying on streets unattended for mths n yrs together... getting to eat maybe once in couple of days… and the second type was people who worked n worked for say 50 rupees a day and also had a family to look after… wht was the purpose of such people in life??? I got the answer for the second type as soon as I reached home n saw my daughter standing at the door…. It doesn’t matter how much one has to slog the whole day, if at the end of d day we see a smile on our childrens face all is forgotten… but then the first type… they die a slow n prolonged death of hunger, diseases, etc. some say it’s their sins of previous life… but then y does one has to suffer for things done in previous life??? Isn’t it logical that a person pays for his/her sins in the same life???... maybe ill find the answer to this n many other such questions someday…
