We’ve already seen TTSP once before.
But this was echoed several centuries ago by the wise Birbal.
King Akbar once asked him, “What is it that will make an unhappy man happy, and a happy man unhappy?”.
Birbal thought for a moment and replied, “This too shall pass!”, indicating that everything is transitory only.
If a moment seems too good, and a happy man is revelling in that moment, that moment will soon pass. And likewise for the unhappy man, who is extrapolating his life to constantly get worser and worser. But as we well know, TTSP!
