WHATEVER WILL BE, WILL BE
The opposite of the verb to lessen is increase. The verb to lessen comes from the word “little” and its comparative form “less”. Whatever will be, will be, in Spanish is “sea lo que sea, será” and It means that it’s going to be what it has to be, you can’t do anything to change what is going to be. The song wants to mean that she doesn't know what her life will be like and she asked her mother, and then her child asked her the same question that she asked her mother.
