Can one change future events indicated by the palm lines?
Yes, it is indeed possible to do so. What is shown by the palm lines today is due to who and what we are, and will show the outcome of the life if we do not make any changes to our outlook and attitudes. The same logic says that it should be possible to do things the other way around, i.e. change our outlook and attitudes, which, in turn, change our palm lines, which then reflect a different future outcome.
