Nature rarely speaks.A whirlwind doesn't even last a whole morning.A rainstorm starts and ends in a single day.
Such things are made by heaven and earth.If heaven and earth can't make a storm last,how can you?
All that which has a beginning has to end no matter when and where. Anything with a beginning cant last forever and so naturally cant have a hold on the everlasting eternity. Impermanent cant offer stability but yes permanent is the best platform to deal with the impermanent changes seen and presented to us in our day to day living. The greater the rooting, better the stability.
