Do you Believe in KARMA?

I just looked up on Karma on Google and was astonished to see many forms of karma, interesting few that met my eyes 😉
Fanpage karma, Social Media Karma, Page Karma, Campus Karma and many more-phew- let me stop thereCEQUySQWEAIy6vJ.jpg

We see a lot of quotes on social media and below are the posts on Karma that I see most often.

But,

What is this Karma and Who does it?
Does it apply to us?
How can we get out of it?
How do we know what is good karma?
Good and Bad is so subjective, what is right according to Karma?
Who is responsible for this Karma phenomenon?
Is it God, then isn’t he partial because we see bad people enjoying good karma?
What all falls under the purview of karma?
