... thinking about the things that happened in the past,
especially when it's done in an obsessive mode, as opposed to
dealing with the 'present'
it's a questionable comment, and usually "has an agenda"
when people use it
it *can* however, yield insights to help peopple
understand what's going on in their "now"
dunno for sure tho
mebbe it's related to this:
If we are concerned about 'what created the world?' and 'why are we here?' then consider the parable of the poison arrow.
A man went to the Buddha insisting on answers to these questions, but the Buddha instead put a question to him: "If you were shot by a poison arrow, and a doctor was summoned to extract it, what would you do? Would you ask such questions as who shot the arrow, from which tribe did he come, who made the arrow, who made the poison, etc., or would you have the doctor immediately pull out the arrow?"
"Of course," replied the man, "I would have the arrow pulled out as quickly as possible." The Buddha concluded, "That is wise, for the task before us is the solving of life's problems; until the problems are solved, these questions are of secondary importance."
