"I was eager to make money, and had a strong desire of lust"
And this lessening of greed and lust is due to FG. How about due to getting older and wiser. I know many people that had lust...and they grew out of it....or they got married and out of natural timing, they grew out of it....
While FG MAY have been your road to this, it is by no means the only road or in any way provable to be the best or even a good road.
Then again, if you are willingly giving your money to promote FG, you might as well become detached from a desire for making money since you ARE becoming detached from your actual money.
"now I know the real meaning of life, so I donot care too much about personal gain, I have a heart of helping others."
SO you KNOW the meaning of life - is Monty Python in there somewhere (talk about an arrogant statement). But, seriously, if that is possible here, exactly HOW aside from preaching "Falun Gong" from the rooftops have you started helping others?
"I was very weak when I was a child, now I have kept heathy for 10 years for practicing Falun Dafa."
ANY form of Qi Gong practice or Taijiquan can offer the self same benefits. Again, you have not shown that this is the best or even a good way....simply one of many ways...and from your hero worship, I would say the price is to high.
While attaining selflessness is a good thing, you can't do it by divesting in your own self while investing in the self of another (like Li Hongzhi).
"Falun Dafa's profound teaching and great benefit has made so many practitioners believe this is a righteous practice. "
Now there is a great pice of logical thinking.
Hmmm...and many people in the 1930's in Germany BELIEVED that Hitler was an ok guy to elect. Many people in the US today BELIEVE that what has happened in Guatanamo is no big thing. Many people in the US today BELIEVE that OJ was innocent, that there was/was not a gunman on the grassy knoll, that Bush is a good/horrible president, that there were / were not WMD's in Iraq....ad nauseam
Belief has never made a thing so. Repeating something often and loudly does not make it true...it may make it annoying and it may make it be believed by many...but it can never make something true.
Blinders are interesting....only when they are on horses.
