Emotions cannot be permanent.  That’s why they are called “emotions”–the word comes from “motion,” movement.  They move; hence, they are “emotions”.  From one to another you continually change.

-Osho

Intense emotions have been likened to an ocean wave.   They crash over you and may knock you off your feet,  however, just like a wave, they always recede.  Learning to ride these waves of emotion without “acting out” is a necessary life skill.
