Mettā is likened to a Mother's Love:

 

The Blessed Buddha once said:
As a mother would risk even her own life to protect her only beloved child,
so let us cultivate infinitely divine loving-kindness towards all living beings!

Comments:
A quite tall order, yet softening, embracing, and advantageous for all beings. :-)
