I am a feeling, quite hard to define,
Yet, it's a part of me, in every design.
A love for all, With no limit nor bound,
A force that spreads, without making a sound.
Some try to fake me, for their personal gain,
But my nature is pure, and always will be the same.
I am not quite tangible, nor am I easy to perceive,
Yet, without me, this world would never achieve.
What am I?
