IMAGINATION is the ability to remember things from past and future lives.
A GENIUS is someone who uses it's imagination  to solve different problems. (I used "it" because it can be an animal, as well as a human)
PHILOSOPHY is something that introverted people have came up with, to figure out what's the problem with this world, when, in fact, they were the real problem....too much knowledge and not enough joy.
PSYCHOLOGY is the younger and materialistic sister of philosophy .
ART is an extension of our physical reach.
MEDITATION is the most pure and natural act as a living creature.
JOY is the essence of life.
