"Man has the possibility of existence after death. But possibility is one thing and the realization of the possibility is quite a different thing"

This quote by Bret Harte recommends that while people have the potential to exist after death, it is not a guarantee. Possibility suggests that something is possible, but not necessarily possible. Harte is recommending that while it is possible for human beings to exist after death, it is not a certainty. He is stressing the importance of acknowledging the distinction between potential and truth. He is also recommending that people ought to not take the possibility of life after death for given, but should instead make every effort to make it a reality. This quote encourages us to act in our lives and to maximize our time here on earth, as we can not ensure what will occur after death.
