Passion comes first.
It is centered around you.
It develops from your within.
Passion leads to the focalization of your mental energy in one direction.
It brings you joy and out of friction in other life sectors.
For example, someone may have a frictional home life that he cannot escape from.
Then, he finds passion in his field of work.
Passion leads to joy and frees him from the suffering of other frictions.
So, passion is individual.
It arises from within you and benefits only you. PASSION IS STILL YOURS.
But once you get uplifted and start experiencing mental peace and contentment, your vision expands to include others.
This leads to a higher purpose, focused on others—objects, people, situations, animals, and even the whole world.
PURPOSE IS FOR OTHERS. ( it is more widespread. )
